I keep a prayer list, to help me remember the things that I should bring before the Lord, and to recognize the answers to prayer that he gives. Perhaps you have such a list, as well. A natural consequence of such a list is that we may pray repeatedly for something. But our Lord warned,
Mat 6:7 When ye pray, use not vain repetitions, as the heathen do
Is it wrong to ask repeatedly for something? Should we limit our prayers to, say, three instances (as Paul did for his “thorn in the flesh” in 2 Cor 12:8, and as our Lord in his agony in the Garden of Gethsemene)?
