God wants you to have a living fellowship (vv. 1–3) with Him and His children. In Jesus Christ, He has revealed what true life really is. Even though you cannot see Him and touch Him as the apostles did centuries ago, He can still be real to you as His Holy Spirit opens the Word to your heart.
1 John 1:1-4 NIV
That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked at and our hands have touched—this we proclaim concerning the Word of life. The life appeared; we have seen it and testify to it, and we proclaim to you the eternal life, which was with the Father and has appeared to us. We proclaim to you what we have seen and heard, so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ. We write this to make our joy complete.
1 John 1:5-10 NIV 5 This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. 6 If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth. 7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
- Romans 15:2 NIV Each of us should please our neighbors for their good, to build them up.
- John 13:34-35 NIV “A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.”
8 If we claim to be without sin, we deceive ourselves and the truth is not in us.
- Romans 3:22-24 NIV This righteousness is given through faith in Jesus Christ to all who believe. There is no difference between Jew and Gentile, for all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus.
9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
- Hebrews 4:14-16 NIV Therefore, since we have a great high priest who has ascended into heaven, Jesus the Son of God, let us hold firmly to the faith we profess. For we do not have a high priest who is unable to empathize with our weaknesses, but we have one who has been tempted in every way, just as we are—yet he did not sin. Let us then approach God’s throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need.
10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
