“In my distress I called to the Lord, and he answered me. From deep in the realm of the dead I called for help, and you listened to my cry. You hurled me into the depths, into the very heart of the seas, and the currents swirled about me; all your waves and breakers swept over me. I said, ‘I have been banished from your sight, yet I will look again toward your holy temple.’ The engulfing waters threatened me, the deep surrounded me; seaweed was wrapped around my head. To the roots of the mountains I sank down; the earth beneath barred me in forever. But you, Lord my God, brought my life up from the pit."
“When my life was ebbing away, I remembered you, Lord, and my prayer rose to you, to your holy temple. Those who cling to worthless idols turn away from God’s love for them. But I, with shouts of grateful praise, will sacrifice to you. What I have vowed I will make good. I will say, ‘Salvation comes from the Lord.’” (Jonah 2:2-9)
A Prayer for God's Continued Mercy (Psalm 86 ESV)
Incline your ear, O Lord, and answer me, for I am poor and needy. Preserve my life, for I am godly; save your servant, who trusts in you--you are my God. Be gracious to me, O Lord, for to you do I cry all the day. Gladden the soul of your servant, for to you, O Lord, do I lift up my soul. For you, O Lord, are good and forgiving, abounding in steadfast love to all who call upon you. Give ear, O Lord, to my prayer; listen to my plea for grace. In the day of my trouble I call upon you, for you answer me.
There is none like you among the gods, O Lord, nor are there any works like yours. All the nations you have made shall come and worship before you, O Lord, and shall glorify your name. For you are great and do wondrous things; you alone are God. Teach me your way, O Lord, that I may walk in your truth; unite my heart to fear your name. I give thanks to you, O Lord my God, with my whole heart, and I will glorify your name forever. For great is your steadfast love toward me; you have delivered my soul from the depths of Sheol. O God, insolent men have risen up against me; a band of ruthless men seeks my life, and they do not set you before them. But you, O Lord, are a God merciful and gracious, slow to anger and abounding in steadfast love and faithfulness. Turn to me and be gracious to me; give your strength to your servant, and save the son of your maidservant. Show me a sign of your favor, that those who hate me may see and be put to shame because you, Lord, have helped me and comforted me.
