Faith is a tricky thing – we often find ourselves coming up short when we need it the most. This was no less true for so-called heroes of faith, Abraham and Sarah. Despite tangible (even audible) promises from God, they had broken faith more than once to try to conjure up for themselves what God had told them He would provide. And yet when they found themselves nearly 100 and still without a child together, God came into their age and weariness and intermittent faith and gave them just what He said He would give. The key to our lives is not perfect faith, but it is faith – that ultimate willingness not to count our circumstances, even the longest and hardest ones, as proof that God is not coming.
