He did not weaken in faith when he considered his own body, which was as good as dead (since he was about a hundred years old), or when he considered the barrenness of Sarah’s womb. No unbelief made him waver concerning the promise of God, but he grew strong in his faith as he gave glory to God, fully convinced that God was able to do what he had promised. (Romans 4:19–21)
What does it look like to be convinced that God is able to do what He promises? And what does it look like when what is promised is impossible?
What if someone told you that one day you would be the President or that you would be the Queen? And what if it wasn’t just an offhand comment, but a promise. It would be an impossible promise (maybe not for you, in which case I’m very honored that you are reading my blog).
Abraham was promised something impossible, but He was convinced in God’s faithfulness to keep His promises. There were a lot of details that didn’t make sense – a lot of good practical reasons to doubt the Word of the Lord – but Abraham persevered in faith. God’s grace allowed Abraham to believe and grow stronger in His belief that God would keep His promise.
This active believing was counted to Abraham as righteousness. God wrote out the storyline (Abraham would be the father of nations) and then by His grace Abraham lived out the impossible story by His belief that it was true.
Abraham had no idea of knowing what the promises would look like, but he knew what God’s faithfulness looked like – steadfast, sure, steady, true.
Sometimes, we are consumed with figuring out what the promises will look like when they are fulfilled. How will God show Himself faithful in finding me a job? How will God’s promise be fulfilled in my friendships? How can God be faithful to overcome the evil in the world and dispel the lies? How do I believe what He promises about eternity?
What will His fulfilled promises look like in my life – in those impossible things?
God’s faithfulness to keep every promise He has ever made gives us a clear picture of the Promise Keeper. Sometimes we are not meant to see what those impossible promises look like, but we are always meant to see who holds the promises secure.
Our faith sees this Promise Keeper and actively believes in His faithfulness.
Abraham could never have imagined what God was promising – what it would look like. He never would have expected that Christ would come as a result of God’s promise and die to demonstrate His faithfulness and mercy. In Christ, God made a way for us and proved His ultimate promise keeping in the most impossible situation: satisfying the debt we owed and securing our place with Him for eternity.
