We serve a God that is a covenant keeping God. A God that has backed everything that He has said that He would give us with a promise and an oath. Both of these things, the Bible says are immutable (or unchangeable). That just means that when He makes you a promise, that’s backed by His oath, you can take it to the bank. You see, when you’re trying to determine whether or not you can count on someone, you have to consider two things. First, are they trustworthy? In other words, do they keep their work. Well, the Bible informs us that it is impossible for God to lie, so we know that He’s trustworthy. He also backed the word by His promise and his oath. That’s another layer of confidence that we have in God.
