It took many years for Abraham to realize the promise of God through the birth of Isaac. What has God promised to birth in our lives that we are holding onto by faith? Or, have we wavered, seeking instead to birth something in our own power?
We all have "Ishmaels" that we have tried to give to God in place of our Isaacs. However, God is faithful and will keep His promise even when we sometimes lack faith. Where is the promise of salvation for our children? Where is vision we once had for ministry? What happened to that healing for ourselves or a loved one we were sure God desired? It is not ours to question, only to believe. Like Abraham, we must repent for our Ishmaels and continue to grow strong in faith, giving glory to God. In due season, we will reap the promises of God because He cannot deny Himself.
