God will come at the perfect time. Just as there is no 7:77 on a clock so to will we not be able to figure out with the limited knowledge we have when his return will be, our knowledge is so rudimenty compared to the perfect. The Lord lives beyound the bounds of time. We may have a general idea of when it will occur based on the clues he has given us in scriputure. But only God knows for he is perfect. 7 represents perfection, and three sevens represent complete perfection.
 
We have imitation jackpots on earth like 777 on a slot machine. But His 7:77 will be the real jackpot. He will be the one pulling the lever, not us. So let him pull on you till you give all the stuff stuck down in your pockets, till even the cob webs of the past that lie in your crawl space are cleaned out. You know, its the cob webs of the past that keep messing up the present. Let him make our hearts perfect like his. Then even the crawl spaces of our hearts will be clean and we can enjoy the peace he offers us now.
