A mark of a true Christian is that he or she continues to be convicted of past and present sins as the Holy Spirit continues working. Rejoice, because that shows you’re growing! Indeed, our maturing in the Lord will continue as long as we live until we’re glorified in His presence. That which He began in you He will perfect at that day!
"Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ."
