In Genesis 21-22, we see the promise of a son fulfilled in the birth of Abraham's son Isaac. In the midst of this, God shows care and concern even for the well-being of Ishmael, and we also see that God's blessing and presence in lives ought to be evident. Then, God asks the unthinkable: he tells Abraham to sacrifice the son he waited 25 years for. The passage reminds us that God desires our hearts and that our response to God must always be obedience and worship, for he wants what is ultimately best for us. Pray that God would test your heart and reveal to you where you hold back and are disobedient, that you may be cleaned and purified and be able to walk in obedience and in worshipful response to the work He does in your life.
