1 John 3:3 And everyone who has this hope in Him purifies himself, just as He is pure.
What does it mean to be pure? Can a filthy sinner ever be made pure? Who or what can purify us? What does a pure life look like? All excellent questions that should be answered. It does not mean, more good than bad. It cant be achieved by self means. It doesnt resemble some fairy tale fabricated life. Recieving Jesus into our lives is the only way to purify us! His word washes the filth of sin. To live as He lives is the only way. So we than look like Christ! The pure in heart are the only ones who can see God, because God is pure.
