Overcoming the World
1Everyone who believes that Jesus is the Christ has been born of  God, and everyone who loves the Father also loves those born of Him. 
2By this we know that we love the children  of God: when we love  God and keep His  commandments. 
3For this is the love  of God, that we keep His  commandments. And His  commandments are not burdensome, 
4because everyone  born of  God overcomes the world. And this is the victory that has overcome the world: our  faith.
5Who then   overcomes the world? Only  he who believes that Jesus is the Son  of God. 
6This is the One who came by water and blood, Jesus Christ— not by  water alone, but by  water and   blood. And it is the Spirit who testifies to this, because the Spirit is the truth. 
7For there are three  that testify: 
8the Spirit,  the water, and the blood— and these three are in  agreement.
Jesus is the Son of God
9Even if we accept   human testimony, the testimony  of God is greater. For this is the testimony that  God has given about His  Son. 
10Whoever believes in the Son  of God has this testimony within him; whoever  does not believe  God has made Him out to be a liar, because  he has not believed in the testimony that  God has given about His  Son. 
11And this is that testimony:   God has given us eternal life, and this  life is in His  Son. 
12Whoever has the Son has  life; whoever  does not have the Son  of God  does not have  life.
Purpose and Concluding Remarks
13I have written these things to you who believe in the name of the Son  of God, so that you may know that you have eternal life. 
14And this is the confidence that we have before Him:  If we ask anything according to His  will, He hears us. 
15And if we know that He hears us in whatever  we ask, we know that we already possess what   we have asked of Him.
16If anyone sees his  brother committing a sin not leading to death, he should ask God,  who will give  life to those who commit this kind of sin.    There is a sin that leads to death;  I am not saying  he should ask regarding that sin. 
17All unrighteousness is sin, yet there is sin  that does not lead to death.
18We know that anyone  born of  God  does not keep on sinning;  the One who was born of  God protects him, and the evil one  cannot touch him. 
19We know that we are of  God, and that the whole world is under the power of the evil one. 
20And we know 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— in His  Son Jesus Christ. He is the TRUE God and eternal life.
21Little children, keep yourselves from  idols.
