We shouldn’t punish ourselves for our past sins, but we shouldn’t forget them either. Remembering past sins can help us stay humble. And staying humble can help us avoid future sins.
Remembering how foolish we’ve been in the past reminds us not to be a fool now. It also makes us grateful for what we have and less likely to have a sense of entitlement.
If we forget about our past sins or pretend they never happened we may be more likely to have a self-righteous attitude — slow to forgive the sins of others, while blind to our own. We should forgive ourselves, but we should never forget that there was much to be forgiven.
Live strong, but be humble.
