We often think receiving what we’ve been guaranteed ought to be a cakewalk, but Scripture shows the opposite is more often true. The most profound things God promised were often fulfilled against the greatest odds and through the most difficult hardships. To God, faith is often the point — God does nothing cheaply. Perhaps the divine nature of a promise fulfilled guarantees its expense. We may receive a hundred unexpected things from God with delightful ease while the fulfillment of some of the things we believe He promised us proves virtually impossible. You see, the impossibility is what makes the fulfillment of the promise fall under the God category. God makes promises man simply can’t keep.
–Beth Moore in “The Patriarchs: Encountering the God of Abraham, Isaac and Jacob”
