I the Lord do not change.
“I am the Alpha and the Omega,” says the Lord God, who is and who was and who is to come, the Almighty.
I had a friend who was described to me as one who “never lands.” What I think that meant was that this particular person would talk, and talk, and talk, and never reach a firm conclusion. He had a difficult time of landing on a particular idea or conviction without many, many, many equivocations to his main point. “He never lands,” seemed at the time to describe this man to a tee.
That’s definitely not God. God never changes. God is the One who is, and who was, and who is to come; the same yesterday, today, and forever and evermore (Hebrews 13:8). He doesn’t change; he is no shifting shadow. God is the rock. He is the one who is – totally apart from anyone’s acknowledgement. He is the one with whom we all will have to do.
This is good news. For God’s changeless nature means that his promises are completely reliable. It means that there will not be a whimsical last-minute default or a failure of nerve in the face of challenges or inconvenience. It means that if we give our lives for the sake of the Gospel, or look to God’s ultimate vindication instead of easy, short-term benefits, we will not be disappointed.
Malachi goes on to say that because of the changeless nature of God we are not consumed. God has landed on this truth: whoever believes in him will be saved. We can count on that, and rejoice in hope of his salvation.
