"Lord Jesus, you are my hope and salvation. Be the ruler of my heart and the master of my home. May there be nothing in my life that is not under your lordship."

Psalm 89:20-26

20 I have found David, my servant; with my holy oil I have anointed him;
21 so that my hand shall ever abide with him, my arm also shall strengthen him. 22 The enemy shall not outwit him, the wicked shall not humble him.
23 I will crush his foes before him and strike down those who hate him.
24 My faithfulness and my steadfast love shall be with him, and in my name shall his horn be exalted.
25 I will set his hand on the sea and his right hand on the rivers.
26 He shall cry to me, `Thou art my Father, my God, and the Rock of my salvation.'
