In Genesis 16:1-16 Abram foolishly listens to his wife and takes Hagar as a second wife to produce a male child. Abram sins doubly by agreeing to the plan and then allowing his new wife to be sent away. Hagar sins in her pride over Sarai. Sarai sins in suggesting the idea in the first place. All of this leads to rupture in the family. Yet, in the midst of all of this sin, God comes graciously to Hagar and shows that grace will be shown to the Gentiles in exile when they turn to God. God uses the foolishness and sin of all involved to foreshadow the glorious ingathering of the nations through Christ, showing the wonder of His unsearchable wisdom.
