After thirteen years of silence, during which Abram had to learn to wait on Gods timing, the Lord finally appeared with changes and challenges. God changed Abrams and Sarais names to Abraham and Sarah, instituted the mark of circumcision, and extended promises that would make any levelheaded person laugh in disbelief. Yet Abrahams faith and obedience reflected a man who had cultivated deep roots in his relationship with God. The Patriarchs time in silence wasnt wasted. Through his example, we can learn how to quiet ourselves, listen to Gods voice, overcome doubts, and step out in obedience.
