There are many essential verses in the Bible*, verses that one needs to know in order to understand what Christianity is – and what is God is calling us to. Below are seven key verses.
1. Matthew 22:36-40
36 “Teacher, which is the greatest commandment in the Law?”
37 Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ 38 This is the first and greatest commandment. 39 And the second is like it: ‘Love your neighbor as yourself.’ 40 All the Law and the Prophets hang on these two commandments.” [emphasis added]
Love then is that which underlies all of Christianity. Love here is a bit different than romantic love. St. Augustine defined love as, "to will the good of the other." Love in the Christian sense has to do with treating people decently, with dignity, with kindness and mercy, with fairness, and as though all human beings have an intrinsic value, which, in God's eyes, they do. The "Golden Rule" of Jesus may also be helpful here: "Do to others as you would have them do to you." (Luke 6:31)
If a person claims to align with God but doesn't have love, then perhaps we should ask ourselves if this person really aligns with God. None of us are perfect, so we should have a lot of grace here, but if someone is claiming to really align with God, then they should be really loving. If not, perhaps they are deceiving themselves (or us).
2. John 3:16
16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
So much is packed into this one small verse. Where to begin? First, note that the basis of all that God is doing in the world is love. It is God's care for his children, us, that motivates him. Second note the depth of his care: He gave his son. This isn't like giving a friend a sweater. Jesus died on our behalf. He died to set us free from sin. He died to reconcile us with God. He died so that when we die, we may rise again new life.
Life after death is the great promise of Jesus. An entire book can be written on what it means to have Jesus die for our sins. You'll need to really dig into this subject in order to understand it – and to receive eternal life. For now, know that this one verse summarizes the entire work of God on this earth.
One last note on John 3:16: "Believe in" is a lot different than to merely believe something is factual. For example, if I believe in exercise, that doesn't mean that I merely believe there is such a thing as exercise. The existence of exercise is not really the question. If I really believe in exercise, my life will show it: I will find a way to exercise. I will make exercise a priority, giving it time and attention, incorporating it into my life. We will know who really believes in exercise by how they live their lives. So also with those who believe in God.
3. Romans 3:23
23 for all have sinned and fall short of the glory of God
None of us are perfect. Indeed, if left to our own devices, humanity can go to some very dark places. I have heard of job offers made to poor women in the Philippines to come work in a hotel in the Middle East. However, when the women arrive, they find that it is not so much "hotel work" that they are to do but rather prostitution. Their employers hold their passports, so the women have little choice but to comply. Tricking someone into prostitution is a dark evil, but it is only one such evil. Read about human experimentation on prisoners in the Second World War. Read about slavery and racism. Read about violent crime every day in every newspaper in every city. One need but pick up any newspaper to see the heart of darkness of humanity. There is a flaw in the human heart. Even the relatively "good" among us have this flaw, and we are foolish and self-deceived if we think otherwise. Certainly none of comes even close to God – who always comes from a place of love.
We all fall short, therefore, we are all in the same boat. So rather than picking on immigrants, white males, religious or ethnic minorities, or whatnot (pick your favorite bogeyman), we should know that we all fall short of the perfection of God. The root of the problem isn't whatever bogeyman our society has identified at the moment. Even if we removed every last instance of the aforementioned bogeyman, our world would not instantly turn to paradise. Rather the problem is one intrinsic to humanity. I don't mean to imply that we shouldn't work against societal problems or that we should let criminals run free (hey, we're all the same boat, right?). Rather, I'm speaking about the real problem: the flaw in the human heart. You can't fix a society by eliminating or attacking one set of individuals, be they "left," "right," or any other flavor. The real problem lies embedded in every human heart, and it is that problem that we must address. We should therefore give grace to one another, knowing that we all fall short, and that this shortfall is the real problem in the world.
Though we fall short, there's good news here: Jesus, through his death, paid the price to reconcile us to God.
4. Ephesians 2:8-9
8 For it is by grace you have been saved, through faith – and this is not from yourselves; it is the gift of God – 9 not by works, so that no one can boast. [italics mine]
There is a lot in these verses. Let's look at four key words (italicized above):
First, "saved." What does this mean? The normal course of a human life ends in physical death. However, there's a "special offer" that God makes to a select few on the basis of faith. For those who place their faith in God, eternal life with God, a life after death, is promised. In other words, through our faith in God, we can be saved from physical death being the end of life.
Next, "faith." Faith is placing our complete trust or confidence in someone or something. For example, a patient goes in for surgery. During the surgery, they are under general anesthesia, unable to do a thing. They are completely in the hands of the surgeon. They have placed their faith in the surgeon. Likewise, we place our lives in the hands of the great physician, Jesus. Just as a patient looks to a surgeon to heal and restore them, so we look to Jesus. Faith is to trust in and place one's life in the hands of Jesus. This is what it means to truly believe in Jesus.
Then, "grace." Grace is something undeserved given out of kindness, love, or mercy. This may sound like a trivial example, but recently I noticed my daughter's water bottle really could use a wash. She's a teenager; she's old enough; her bottle is her responsibility. However, I saw the need, and I washed my daughter's water bottle. She didn't do anything to earn it. I did it out of kindness and love for my daughter. So it is with God and being saved. There's nothing we humans can do to earn being saved. Being saved is not payment of wages owed. Being saved is a gift from God stemming from God's kindness, God's grace, God's love. He gives it to those who have faith in him, those who have placed their lives in his hands, those who have a relationship with him. Just as I washed my daughter's bottle out of love, so also God saves us out of his love for us.
Lastly, "works." Works would include being charitable, being kind, obeying the law, doing what is right, keeping religious customs and observances, reading the Bible, volunteering at church or a charity, etc. These are all good things, but they don't earn being saved. There is nothing we can do to earn being saved. We do these things because we believe they are right and good not because they will earn us being saved.
5. John 14:1-3
1 “Do not let your hearts be troubled. You believe in God; believe also in me. 2 My Father’s house has many rooms; if that were not so, would I have told you that I am going there to prepare a place for you? 3 And if I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am."
This is the great promise of God, here in Jesus' own words: "I will come back and take you to be with me." The night before Jesus was crucified, he spoke to his disciples, knowing that he would soon be executed, "I will come back and take you to be with me that you also may be where I am." Exactly where this is, we do not know. Is it some spiritual existence? Is it physical? The Bible talks of a "new Heaven and a new earth," but exactly what this is we do not know. However, we have seen the testimony of Jesus' life, a testimony to his goodness and of the Father's. We have also seen the testimony of his death. As it is written, "Greater love has no one than this: to lay down one’s life for one’s friends" (John 15:13). There is no greater love nor sincerity than to give up one's very life for another. We have seen the testimony of his resurrection. If even death has no power over Jesus. Because of the testimony of his life (goodness), death (sincerity, devotion, and love), and resurrection (he really is God!), we have confidence that Jesus can fulfill his promise.
6. Psalm 14:2
2 The Lord looks down from heaven on all mankind to see if there are any who understand, any who seek God.
None of us today are eye witnesses of the resurrection. We have come to believe on the basis of eye witnesses testimony, but no one alive today is an actual eye witness. So, what is it that causes us to seek God and to come to believe? Perhaps it is as in Ecclesiastes 3:11, "you have set eternity in the human heart." There something in some of us, something that attracts us to or drives us to God.
And you? What does your heart say about this life? Does injustice (name your evil) cry out for Justice? Is life ending in physical death life as it should be? There's got to be more to life than this. Let your discontent with death and injustice, your discontent the world lead your heart to God. The chief purpose of this life is to do good and seek God.
7. Romans 12:2
2 Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will.
The way of the world is self and ego. The presence of great ego (me! me! me!) is typically the absence of God.
The way of Jesus is love. Jesus calls us to consider others as just as valuable as we are, to love our neighbor as our self. Every day, we, with the Holy Spirit, learn to be a bit more like Jesus, the perfect person, who always comes from a place of love. Transforming to the way of Jesus is the life work of those who follow Jesus.
