1. The psalmist here claims to know God as his shepherd (v.1). 2. He recalls his experience of the good things God had done for him as his shepherd (vv.2-3,5). 3. He reasons from this that he would lack no good thing (v.1), that he need not fear any evil (v.4), that God will never leave or forsake him with his mercy; and so he decides never to leave God by leaving the path of duty (v.6). As in the previous psalm he described Christ dying for his sheep, so here he describes Christians as receiving the benefits of all the care and tenderness of God, our good and great shepherd.
