It is true that we are new creations in Christ (2 Corinthians:5:17) and that old things are passed away and all things are become new. It is also clear, however, that we are accountable for the choices we have made in the past. The prisoner who comes to the Lord must still serve out his sentence. The debtor must still repay his physical debts, and the father of children is still responsible for them, whether married to their mother or not. What has been wiped clean is our debt of sin and the judgment that hung over our heads (Colossians:2:14). The consequences of past failures may now be addressed with the confidence of a new creation.
"Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new."
