We move from salvation and the assurance of salvation to Satan and the activity of Satan. Sarai came with temptation - "Why don't you sleep with my slave? Maybe I can build a family through her." Abram gave in to temptation -"Abram agreed with Sarai (Genesis 16:2). The evil influence of Sarai continued: "Sarai mistreated Hagar so much that she ran away" (Genesis 16:6). When we read of Satan and his activity, we must not imagine, for a moment, that Satan wins the victory over the Lord and His purpose of salvation. This becomes clear as the story develops. The Lord's purpose will not be thwarted by the activity of Satan. The "Almighty Lord" will be victorious. This chapter ends with the birth of Ishmael. It is not a high- point in the purpose of God. It is a sign that Satan is trying to overthrow God and His gracious purpose. This leads to a 13-year gap in God's speaking to Abraham (Genesis 16:16-17:1), but that is only a hiccup, after which God continues to carry forward His great purpose of salvation.
