Why did God leave Adam? He crucified and buried him, yet why did God leave Adam still available to his own will? Why is the enemy not driven out totally in experience as he is in position? Why does God just drive him out little by little (Deuteronomy 7:22)? Why grow in grace? Why can’t we just arrive? Why do we have to decrease ( John 3:30)? Why must we always learn obedience? Why can’t we confess that we have arrived? Why press on? Can’t we say we made it while living in humanity?
The reason is that God does not want spiritual robots, but a people who will experience a grace that is sufficient. He desires His strength to be made perfect in our weakness instead of a people who have strength but no weakness. God does not make us perfect, because He wants His grace to accept us as perfect before we are perfect, lest we misunderstand the revelation of grace. Otherwise, we would not understand growth in perfection.
God accepts us before we are acceptable (Ephesians 1:6). He provides a perfect record before the record is perfect. He sees us as mature when we are yet immature (Colossians 2:10). He reckons us dead to sin while we yet fail (Romans 6:11; Philippians 3:15). Grace is sufficient to see us living in Christ though at times we do live in Adam. Our experience denies Christ’s provision, but God’s grace establishes His provision as our experience. God’s grace cannot impute sin. It is sufficient. His strength is made perfect in all forms of weakness.
