Have you ever been with people who cannot make up their minds? You ask, “Where do you want to sit?” and they ponder this as though the fate of the free world rested upon their answer: “Um, how about there…no, over there…no, wait…” Our natural tendency is to waver. We waver over where to eat, what to wear, and when to make a call. Some even waver over their eternal destination. Someone asks: “Do you know for certain that you are going to heaven?” Waverers grimace, twist their hands and say: “Uh, I sure hope so…maybe. I guess.” Waverers have a hard time moving forward with anything, including faith.
Abraham is a great example to us of someone who could have wavered, but didn’t. God had given Abraham a promise: “You will be the father of many nations.” Abe was old and childless when this promise came. Yet, for twenty-five years he held on to it. He had heard from God and nothing could convince him otherwise. Verse 21 tells us how he kept from wavering. It says, “He was fully convinced that God is able to do whatever he promises.” Before we can believe God, we must know what He says. We must accept His offer to be Lord of our lives (Luke 9:23) and spend our days learning to follow Him. The more we know Him, the more we trust Him. As our faith grows, we become like Abraham, fully convinced that God is able to do whatever he promises. Faith is believing promises before we see them. God honors such faith and strengthens those who persevere in it.
