About overcoming the sin of the world:

So I turned to the Lord God and pleaded with him in prayer and petition, in fasting, and in sackcloth and ashes. � I prayed to the Lord my God and confessed: "O Lord, the great and awesome God, who keeps his covenant of love with all who love him and obey his commands, � we have sinned and done wrong. We have been wicked and have rebelled; we have turned away from your commands and laws. � The sting of death is sin, and the power of sin is the law. � for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. � Who is it that overcomes the world? Only he who believes that Jesus is the Son of God. � This is the one who came by water and blood--Jesus Christ. He did not come by water only, but by water and blood. And it is the Spirit who testifies, because the Spirit is the truth. � For there are three that testify: � the Spirit, the water and the blood; and the three are in agreement. � And if we know that he hears us--whatever we ask--we know that we have what we asked of him. �
