You forgave the iniquity of your people and covered all their sins. Psalms 85:2 NIV
Since Adam and Eve sinned, the LORD has been in the business of forgiving and guiding us to righteousness. When we repent of our sins, we are covered with His blood that was shed for us as the Lamb of God on the cross. Your sins are erased. Ask God for the strength to go and sin no more.
