I am not sure that restoration is an actual Bible term but I will check on it. But people
need to have a term to mean that they are back to God which is what repentance is.
When we repent we become justified which is just as if I'd never sinned. Gordon Fergison
(please excuse spelling) has a book about the subject and it helped me to understand
repentance and justification. Restoration is used in the old testament to talk about putting
back God's Temple mostly. I didn't see a new testament scripture about it. We use the word restore
to mean to come back to the fellowship of believers. But I do see in Galatians 6:1 that we are to restore someone gently
if they are caught in sin. The key word is gently also to be careful not to be tempted ourselves.
Restoring is to bring back to a former status. I don't see that God wants us to "beat ourselves up" over
when we have sinned and want to change(repent). That is an opinion but not a true fact of scripture of God.
He wants a relationship with us.
