If we needed to continue seeking more forgiveness from God for every time we fell short, then the second covenant established by Jesus was a failed experiment. Repeated forgiveness is what the Jews pursued under the first covenant (before the cross).
If more forgiveness needs to be dispersed by God, then Jesus would need to keep offering Himself again and again. We have a better proclamation inside of a new and better covenant. Sins weren’t just covered; they were taken away.
Still seeking more forgiveness from God? You could probably use some good news. God’s complete forgiveness for sin occurred once for all.
When sin has been removed and taken away to be remembered no more, the forgiveness offerings are no longer needed. We no longer seek what we already possess.
