It can be easy to read the Old Testament and think that there are somehow two Gods; the Old Testament God of judgement who suddenly changes his spots and becomes the God of Love in the New Testament.
This is not so, God is same yesterday, today, and forever, and today’s Psalm (from the Old Testament) is one of the great “love” passages of all the bible. Part of the nature of our Rock of Ages, who doesn’t change is to be all all-present (omnipresent), all-knowing (omniscient), and all-powerful (omnipotent).
