If the Lord is our shepherd, why are we still in want?

Many of us say the Lord is our shepherd and we are still in want. The reason is this; He makes us lie down in green pastures, but our restless souls refuse to be quiet. He leads us by still waters, but we refuse to drink. He restores our souls, yet we are never satisfied. He leads us in the paths of righteousness, but our rebellious souls leads us astray. He walks with us through all the valleys of the shadow of death, yet we are still afraid. His rod and staff are there to comfort us, yet we refuse to accept them. He prepares tables before us in the presence of our enemies, but we are not humble enough to sit down and eat. He anoints our heads with oil so that our cups could run over, but many of our cups are empty because they are turned down, and surely goodness and mercy cannot follow us all the days of our lives if we refuse to dwell in the house of the Lord forever and ever. Amen!
