Paul says, "I focus on one thing; forgetting the past and looking forward to what lies ahead (Phil 3:13). When we have sinned in the past, we need to renounce it, forget and let the Lord begin His healing within us. The Devil however, likes to remind us of our sins, shame and regrets so we will live in continuous guilt or fear. The scriptures says that the Lord looks to establish a new covenant with us and He will remember our sins no more (Hebrew 8: 12) - For I will be merciful to their unrighteousness and their sins and the lawless deeds I will remember no more.
Paul would have had a list of shame he carried, he prosecuted many Christians before his life in Christ but the Lord graced Him to look ahead and endured suffering for his new faith boldly. Paul chose to forget the past and look ahead & rely on the Lord's promise that his sins are remembered no more.
Do not look back to your past and let it stop your growth in Christ. Jesus has bore all of your sins, shame, fear, regrets and guilts on the cross. He has risen victoriously over all; don't take back the defeat that the Lord has conquered and won for you. The Lord has made us victors through Him. Let us receive His forgiveness, forgive ourselves and look forward to what lies ahead.
Isaiah 43:18-19
Forget the former things; do not dwell on the past. See, I am doing a new thing! Now it springs up; do you not perceive it? I am making a way in the wilderness and streams in the wasteland.
- John W.
