1 John 5:10-13 Whoever believes in the Son of God has the testimony in himself.

I write these things to you who believe in the name of the Son of God that you may know that you have eternal life.

Let's throw in a few verses, for the status of some here:
Romans 10:2-3 For I bear them record that they have a zeal of God, but not according to knowledge. For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.
Galatians 5:1-4 Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage. Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing. For I testify again to every man that is circumcised, that he is a debtor to do the whole law. Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
