Walking with God is not walking before God. God repeatedly promised Abram that his descendants would be countless, like the star in the sky and the dust of the earth. Many years passed and it still hadn’t happened. Abram became impatient and he did a foolish thing. He listened to his wife and had sexual relationship with her maid Hagar. He did have a son through her. But that’s not the one God promised. The son made him heartbroken and his family facing great challenges. He didn’t fully trust in God, walked ahead of God, using the human way to achieve God’s purpose. That’s the reason for his failure. But God’s promise never changes.
Chapter 15: God’s promise to Abram, God’s commitment
Chapter 16: Abram became impatient. Speculation. Man of little faith
Chapter 17: Covenant of God and Abraham. Circumcision. God is faithful and abundant.
