(2Corinthian 5:17) Therefore, if anyone is in Christ, he is a new creation.
A new creation is a total recreation. God doesn’t repair or renovate our life, HE destroys totally and rebuild from ground. HE recreates us! So, stop trying to fix yourself. It nerve works. It is a fake change for a short time. Only God can remake us and permanently totally change us.
When God’s presence came, Saul became Paul (Acts 8). It is God’s miracle, it is not a slow process, it is an instant change in Saul’s life.
