Has GOD made promises in HIS word? Yes, HE keeps HIS promises. And, HE is PERFECT. HE is so PERFECT in fact that there would be no reason for HIM to have to go "back in time" because anything HE does/says/sets, is. HE cannot make mistakes. That is hard to fathom and a blessing to believe!! I don't know anyone around me who is like this. I get so excited and awe struck when I think about how PERFECT our LORD is. Just writing about it is a joy!
What I have written does not mean much w/out verses, but this is what I believe. When I was at Sunday school last weekend, we were told that GOD keeps HIS promises. There you go, I don't know if I am on the same page as the rest of you, but it just seems simple. We are not given "time traveling" options so, why don't we just go with what we know as day to day folks. (of course this is kind of vague to say)
I guess in asking these questions though, it gets us thinking about how AWESOME our GOD truly is and we get to talk/write/think about our FATHER. Good times.
