Under the Unpredictable Plant
 When my life was fainting away,
I remembered the LORD,
and my prayer came to you,
into your holy temple.
 Those who pay regard to vain idols
forsake their hope of steadfast love.
 But I with the voice of thanksgiving
will sacrifice to you;
what I have vowed I will pay.
Salvation belongs to the LORD!”
– Jonah 2:7-9
The commonest form of prayer in the Psalms is the lament. It is what we would expect, since it is our commonest condition. We are in trouble a lot, so we pray in the lament form a lot. A graduate of the Psalms School of Prayer would know this form best of all, by sheer force of repetition.
Jonah in the belly of the fish was in the worst trouble imaginable. We naturally expect him to pray a lament. What we get, though, is its opposite, a psalm of praise, in the standard thanksgiving form.
Circumstances dictated “lament.” But prayer, while influenced by circumstances, is not determined by them. Jonah, creative in his praying, chose to pray in the form “praise.”
