It is not just that God can time travel, that He can go back to 1776 or jump ahead to 2076 on a whim. God is always at all points in time. He is always at the time and place of your birth, when and where you met your spouse, at the scene of all your sins, of all your hurts, and of all your good deeds.
I like to think of it as Him being in a parallel universe. He is right here, right now, just a little bit out of sight. Jeremiah (1:5) says He knew us before we were formed in our mother’s womb and, at least for Jeremiah, he had plans for Him. But He was not only there then, He is there now.
Yet God says over and over that He will remember our sins no more. The Hebrew writer quotes Jerimiah 31:34 twice. In Chapters 8 and 10 he quotes the Lord as saying, ‘I will remember their sins no more.” He is still there, but He doesn’t “remember” our sins. That is delightful!
And God has been with us throughout our entire lives – including however much of our life still lies ahead. We have heard touching stories of how close twins can be, but we have a friend who is “closer than a brother (Proverbs 18:24)”
