Matthew 12-15 (The Daily Walk Bible).
Matthew 15:21-28 teaches us an important lesson: God may be silent when we pray because he wants us to be persistent. It reminds me of Luke 18:1-7.
“And he told them a parable to the effect that they ought always to pray and not lose heart. He said, ‘In a certain city there was a judge who neither feared God nor respected man. And there was a widow in that city who kept coming to him and saying, “Give me justice against my adversary.” For a while he refused, but afterward he said to himself, Though I neither fear God nor respect man, yet because this widow keeps bothering me, I will give her justice, so that she will not beat me down by her continual coming.’ And the Lord said, ‘Hear what the unrighteous judge says. And will not God give justice to his elect, who cry to him day and night? Will he delay long over them?’”
Persistence in prayer is important. We shouldn’t just assume that God doesn’t want to answer our prayers. It may simply be that God wants us to keep praying!
