Because sometimes the things God ask of us can be overwhelming and will require courage, faith, and strength. Joshua becomes the successor to Moses and was required to lead Israel into the Promised Land, after many battles with the inhabitants of the land. Abraham experienced such a thing, when God asked him to sacrifice his son Isaac, the son of promise, and his posterity; and, a trembling, reluctant Moses was called to deliver Israel out of the hand of Pharaoh. All three men were asked to do things that required faith, strength and courage. The miracle of it all was that God actually performed these great tasks through their obedience and willingness to push fear aside and walk by faith (not by sight). We can also employ these principles in our life and live a life of peace, freedom, security, and prosperity while experiencing the miraculous hand of God in our daily affairs.
