If Psalm 23 asks a question it may be "Who will care for me?"

Provision for our flourishing (verse 2-3)

Phillip Keller writes in his book “A Shepherd Looks at Psalm 23”
“sheep do not lie down easily and will not unless four conditions are met. Because they are timid, they will not lie down if they are afraid. Because they are social animals, they will not lie down if there is friction among the sheep. If flies or parasites trouble them, they will not lie down. Finally, if sheep are anxious about food or hungry, they will not lie down. Rest comes because the shepherd has dealt with fear, friction, flies, and famine.”

Confidence for the future (verse 6)

Romans 8:38-39 NIV
For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.
