The sun rises and sets every day, but will it go on forever? In the first century, many assumed the answer was "yes." The church expected a real change in the world when Jesus returned, but mockers began to ridicule Christians as if the world would never change. Peter wrote:
2 Peter 3:8–9
"Don’t overlook the obvious here, friends. With God, one day is as good as a thousand years, a thousand years as a day. God isn’t late with his promise as some measure lateness. He is restraining himself on account of you, holding back the End because he doesn’t want anyone lost. He’s giving everyone space and time to change."
The Lord is giving time for metanoia—for having a true change of mind. Am I being patient? Am I giving others space and time to repent?
