For 1 Samuel 1:21–2:10, you must explain the place of vows in Israel and how Hannah can rejoice in the Lord whilst giving her son into the care of another family (Eli). You must also consider her prayer for Samuel. What is the reversal that Hannah was looking forward to in her day and age? When will the great reversal finally and ultimately be accomplished? On the basis of the deliverance that Christ has accomplished in the past and will accomplish in the future, we must submit to his rule now and we can do so by giving special attention to the vows and promises that we make.
