When God appeared to Abram and changed his name to Abraham, He shows us three characteristics of Himself. First, He is a God of power, which will always be used for good and never for evil. Second, He is a God of grace. The covenant sign of circumcision pointed to God’s initiative in making and establishing the covenant, and the constant assurance God provides to his children. Third, He is a God of the impossible. Nothing is too hard for the Lord.
