Jesus said, “The time is fulfilled, and the kingdom of God is at hand — repent and believe the Good News!” (Mark 1:15)
Jesus did not say, “The Kingdom of God is at hand — regret and believe the Good News!” The difference between regret and repentance is the difference of an opened door to a new future.
God’s doors, like His mercies, are new every morning.
Frederick Buechner writes, “The sad things that happened long ago will always remain part of who we are just as the glad and gracious things will too, but instead of being a burden of guilt, recrimination and regret that makes us constantly stumble as we go, even the saddest things can become, once we have made peace with them, a source of wisdom and strength for the journey that still lies ahead.”
