Sometimes I joke that I'm going to write a book titled On Time. Those who know me smile because they know I am often late. I rationalize that my lateness is due to optimism, not to lack of trying. I optimistically cling to the faulty belief that “this time” I will be able to get more done in less time than ever before. But I can't, and I don't, so I end up having to apologize yet again for my failure to show up on time.
In contrast, God is always on time. We may think He's late, but He's not. Throughout Scripture we read about people becoming impatient with God’s timing. The Israelites waited and waited for the promised Messiah. Some gave up hope. But Simeon and Anna did not. They were in the temple daily praying and waiting (Luke 2:25–26, 37). And their faith was rewarded. They got to see the infant Jesus when Mary and Joseph brought Him to be dedicated (vv. 27–32, 38).

When we become discouraged because God doesn't respond according to our timetable, Christmas reminds us that “when the set time had fully come, God sent his Son . . . that we might receive adoption to sonship” (Gal. 4:4–5). God’s timing is always perfect, and it is worth the wait.
