SERIES: Godprint: The Life of Abraham
MESSAGE: Genesis 20:1-21:8
SPEAKER: Skip Heitzig
SCRIPTURE: Genesis 20:1-21:8

As believers we are new creations in Christ, however, we still carry around our old nature; the battle between the spirit and the flesh is a struggle for all of us. As we consider the life of Abraham, we see him fall once again into a familiar sin. The consequences of his choices are damaging, hurting others and ruining his testimony before unbelievers. But as we'll see in our text, God is faithful, and causes all things to work together for good for those who love Him and who are called according to His purpose.
