This is eternal life, that they may know you, the only true God, and Jesus Christ whom you have sent.
1 JOHN 1:1-5
We proclaim to you the one who existed from the beginning, whom we have heard and seen. We saw him with our own eyes and touched him with our own hands. He is the Word of life. This one who is life itself was revealed to us, and we have seen him. And now we testify and proclaim to you that he is the one who is eternal life. He was with the Father, and then he was revealed to us. We proclaim to you what we ourselves have actually seen and heard so that you may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ. We are writing these things so that you may fully share our joy.
This is the message we heard from Jesus and now declare to you: God is light, and there is no darkness in him at all.
1 JOHN 2:3
We know that we have come to know him if we keep his commands.
1 JOHN 4:7-8, 13
Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love. . . . This is how we know that we live in him and he in us: He has given us of his Spirit.
I want to know Christ— yes, to know the power of his resurrection and participation in his sufferings, becoming like him in his death.
2 TIMOTHY 1:12
That is why I am suffering as I am. Yet this is no cause for shame, because I know whom I have believed, and am convinced that he is able to guard what I have entrusted to him until that day.
2 PETER 1:3-4, NRSV
His divine power has given us everything needed for life and godliness, through the knowledge of him who called us by his own glory and goodness. Thus he has given us, through these things, his precious and very great promises, so that through them you may escape from the corruption that is in the world because of lust, and may become participants of the divine nature.
