John 21:15-19
When they had finished eating, Jesus said to Simon Peter, “Simon son of John, do you truly love me more than these?”
“Yes, Lord,” he said, “you know that I love you.” Jesus said, “Feed my lambs.”
Again Jesus said, “Simon son of John, do you truly love me?”
He answered, “Yes, Lord, you know that I love you.” Jesus said, “Take care of my sheep.”
The third time he said to him, “Simon son of John, do you love me?”
Peter was hurt because Jesus asked him the third time, “Do you love me?” He said, “Lord, you know all things; you know that I love you.”
Jesus said, “Feed my sheep. I tell you the truth, when you were younger you dressed yourself and went where you wanted; but when you are old you will stretch out your hands, and someone else will dress you and lead you where you do not want to go.” Jesus said this to indicate the kind of death by which Peter would glorify God. Then he said to him, “Follow me!”
Psalm 18:1-29
I love you, O LORD, my strength. The LORD is my rock, my fortress and my deliverer; my God is my rock, in whom I take refuge. He is my shield and the horn of my salvation, my stronghold. I call to the LORD, who is worthy of praise, and I am saved from my enemies.
The cords of death entangled me; the torrents of destruction overwhelmed me. The cords of the grave coiled around me; the snares of death confronted me. In my distress I called to the LORD; I cried to my God for help. From his temple he heard my voice; my cry came before him, into his ears.
The earth trembled and quaked, and the foundations of the mountains shook; they trembled because he was angry. Smoke rose from his nostrils; consuming fire came from his mouth, burning coals blazed out of it. He parted the heavens and came down; dark clouds were under his feet. He mounted the cherubim and flew; he soared on the wings of the wind. He made darkness his covering, his canopy around him – the dark rain clouds of the sky. Out of the brightness of his presence clouds advanced, with hailstones and bolts of lightning. The LORD thundered from heaven; the voice of the Most High resounded. He shot his arrows and scattered the enemies, great bolts of lightning and routed them. The valleys of the sea were exposed and the foundations of the earth laid bare at your rebuke, O LORD, at the blast of breath from your nostrils.
He reached down from on high and took hold of me; he drew me out of deep waters. He rescued me from my powerful enemy, from my foes, who were too strong for me. They confronted me in the day of my disaster, but the LORD was my support. He brought me out into a spacious place; he rescued me because he delighted in me.
The LORD has dealt with me according to my righteousness; according to the cleanness of my hands he has rewarded me. For I have kept the ways of the LORD; I have not done evil by turning from my God. All his laws are before me; I have not turned away from his decrees. I have been blameless before him and have kept myself from sin. The LORD has rewarded me according to my righteousness, according to the cleanness of my hands in his sight.
To the faithful you show yourself faithful, to the blameless you show yourself blameless, to the pure you show yourself pure, but to the crooked you show yourself shrewd. You save the humble but bring low those whose eyes are haughty. You, O LORD, keep my lamp burning; my God turns my darkness into light. With your help I can advance against a troop; with my God I can scale a wall.
