Waiting for God to help us is not easy, but David received four benefits from waiting: God (1) lifted him out of his despair, (2) set his feet on firm ground, (3) established his goings (steadied him as he walked), & (4) gave him a new song.
The religious ritual of David's day involved sacrificing animals in the Tabernacle. Today we often make rituals of going to church, taking communion, or paying tithe. Make sure you give God the obedience & life-long service he desires from you.
Jesus portrayed this attitude of obeying & serving God (John 4:34;5:30).
God shows his righteousness & faithfulness to his people in his offer of salvation. David boldly proclaimed this to those around him. We want to tell other people what God has done for us. Since it is natural to share a good bargain with others or recommend a skillful doctor, then we should also feel natural sharing what God has done for us.
People who are faithful to us accept & love us, even when we are unloveable. Faithful people keep their promises whether promises of support or marriage vows. He loves us in spite of our constant bent toward sin, & he keeps all his promises he has made to us, even when we break our promises to him.
