Here's today's devotion from the Life Application Study Bible:
But you must not forget this one thing, dear friends: A day is like a thousand years to the Lord, and a thousand years is like a day. The Lord isn’t really being slow about his promise, as some people think. No, he is being patient for your sake. He does not want anyone to be destroyed, but wants everyone to repent. 2 Peter 3:8-9, NLT
God may have seemed slow to these believers as they faced persecution every day and longed to be delivered. But God is not slow; he just is not on our timetable. Jesus is waiting so that more sinners will repent and turn to him.
We must not sit and wait for Christ to return, but we should live with the realization that time is short and that we have important work to do. Be ready to meet Christ any time, even today; yet plan your course of service as though he may not return for many years.
