I strongly disagree with that! Apparently, God has and will forgive all of our sins and rebellious ways against Him. How?
This singer: https://youtu.be/1Ben2wwGyOk is right on track.
Psalm 119:9-16 NIV
 How can a young person stay on the path of purity? By living according to your word.  I seek you with all my heart; do not let me stray from your commands.  I have hidden your word in my heart that I might not sin against you.  Praise be to you, Lord; teach me your decrees.  With my lips I recount all the laws that come from your mouth.  I rejoice in following your statutes as one rejoices in great riches.  I meditate on your precepts and consider your ways.  I delight in your decrees; I will not neglect your word.
When we sin, we are going in the wrong direction and need to turn around.
What I am saying is that sin separates us from God but Jesus made a way possible for us that we can enter the Holy of Holies and be forgiven. See my post: https://iluvbingjcsbride.blogspot.com/2014/01/what-life-should-look-like-truth-behind.html for further details on life.
