Before we were all saved, every one has had a past life. We all commit sins, in our life as an unbelievers included things that weren’t pleasing to God.
When you become saved and born again, the Bible tells us that we have now of new creations in Jesus Christ.
Our dirty slates are wiped fully clean, and we are now been given a brand new start in this life if we are willing to properly work with grace, and power.
