One time a lady friend of ours said ” I know my husband, I will say this over and over again until he gets tired of hearing it; then he will buy it”. She had wanted an item bought for their house but her husband kept putting it off. But she knew what to do to have it bought. In Luke 18: 1-8, Jesus tells a parable about a persistent widow who kept asking for justice from a judge. After several attempts , the judge granted the lady her wishes. After the parable, Jesus asks if God will keep putting off His chosen ones who cry out to Him day and night. He adds on that God will see that they get justice, quickly.
Let`s not grow weary, persistent prayer avails answers.
