Well first we can not take one scripture and make it stand alone, we must go by the whole word of God;
Luke 13:3
I tell you, no! But unless you repent, you too will all perish.
2 Peter 1:9
But whoever does not have them is nearsighted and blind, forgetting that they have been cleansed from their past sins.
Romans 3:25
Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God;
1 John 1:7-10
7 But 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.
8 If we claim to be without sin, we deceive ourselves and the truth is not in us.9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
