Belief is not about the existence of God!
I now want to unpack what it means that Abraham ‘believed’. Many people I talk to think that ‘believing’ means believing in the existence of God. How many times have I heard “Oh I believe in God” – meaning “I believe that God exists”. Somehow we seem to think that God is impressed and delighted when we affirm His existence. But in fact the Bible is far more muted on that. It states that:
You believe that there is one God. Good! Even the demons believe that—and shudder. (James 2:19)
According to the Bible, simply believing that God exists puts us in the same league as the Devil. I will leave it to you to judge for yourself how much assurance you want to take from that. Now it is true that Abraham believed in God’s existence, but that is not at all the point in this encounter.
The reality facing Abraham was that he had no son and he was in his 80’s. In this exchange, God, as he had done several times before, had just finished promising Abraham that He would give him one. It was that promise which thrust Abraham unto a Crossroads of Decision. His choice was not about believing in the existence of God or not, but whether he would believe that particular promise that this God had given him – or not.
And in that decision Abraham chose to believe. He trusted that God would fulfill that promise to him. Belief, in this account, is synonymous with trust. Abraham chose to trust God in this matter that was very important to him – which solely by looking on the surface of things did not look very hopeful.
GOD requires Belief and Trust from us…not one without the other.
So Abraham chose to believe that promise of a son. In return God gave him something in addition to the promise. He gave him – the word used is ‘credited’ – righteousness. In the end Abraham got both the fulfilled promise (a son from whom a great nation would come) with righteousness almost seemingly thrown in as a side-thought.
