With God’s timing we may overlook calm serenity as lack of intervention. All of God’s promises will be accomplished in His correct timing (chronos). He will at times wait for a different timing (kairos) which means all things are correctly lined up. In the chronological realm it may feel too long or too short. He will ultimately fulfill His purposes for our good. – Teresa

2 Peter 3: 8-10 (ESV)

8 But do not overlook this one fact, beloved, that with the Lord one day is as a thousand years, and a thousand years as one day. 9 The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you,[a] not wishing that any should perish, but that all should reach repentance. 10 But the day of the Lord will come like a thief, and then the heavens will pass away with a roar, and the heavenly bodies[b] will be burned up and dissolved, and the earth and the works that are done on it will be exposed.[c]
