Isaiah 59:2 - "But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear."

Romans 3:10-12 - "As it is written, There is none righteous, no, not one: There is none that understandeth, there is none that seeketh after God. They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one."

Romans 5:1 - "Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:"

Colossians 1:19-22 - "For it pleased the Father that in him should all fulness dwell; And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven. And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled in the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight:"

1 Peter 3:18 - "For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:"

These are a few verses that highlight the message that sin separates us from God, and it is only through faith in Jesus Christ that we can be reconciled to Him and have our sins covered.
