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.
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
The world and its desires pass away, but the man who does the will of God lives forever.
He who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil's work.
This is how we know we are in him: Whoever claims to live in him must walk as Jesus did.
If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him?
He [Jesus] is the atoning sacrifice for our sins, and not only ours but also for the sins of the whole world.
We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true — even in his Son Jesus Christ. He is the true God and eternal life.
There is no fear in love. But perfect love drives out fear, because fear has to do with punishment. The one who fears is not made perfect in love.
Do not love the world or anything in the world. If anyone loves the world, the love of the Father is not in him. For everything in the world - the cravings of sinful man, the lust of his eyes and the boasting of what he has and does - comes not from the Father but from the world.
