Live thoughtfully today and you won't have to live regretfully tomorrow."
My thoughts
Too many people spend their twilight years regretting missed opportunities, poor choices, honest mistakes, and frank sin. Yes, we should regret, and face the consequences of our wrongs, minor, or serious. However that doesn't mean we should be paralysed by them.
It is NEVER too late. Sure the person we offended may have died. We may have lost contact with the person we need to reconcile with. But forgiveness is for US as well as them.
We can claim and experience God's forgiveness. We can forgive others, even if they do not, or cannot respond. We can, with God's help, change the inner conditions that created the problem and move forward. Even in old age, we can pursue our dreams. Never give up, because it's never too late.
