Many sentences of the Bible easily stand alone. Read or recall one of them and let its theme or topic guide your prayer.
Here’s an example.
First, think of someone (your cousin, the mayor, a yak herdsman in Tibet, or just anyone).
Second, either a) recall a Bible sentence from memory, or b) open the Bible and read a sentence or two.
If the Bible sentence you are reading is about healing, pray for your cousin’s health. If it is about God’s glory, pray that the mayor will experience that glory. If it is about sin, pray for the yak herdsman’s forgiveness. Etc.
Bible verse prayers are full of insight, surprise and awesome power. Enjoy!
