I remember the King James version of James 5:16, “The effectual fervent prayer of a righteous man availeth much.” Though some of the language is outdated, surely the thought is as fresh and powerful as ever. We understand what this means. It means that we can and should pray much. And, we should pray for others often and fervently and see how God works through our prayers. I think of this today because I read the story of Isaac and Rebekah this morning. Genesis 25:21 says that Isaac prayed to the Lord for his wife because she was barren. And the Lord heard his prayer, and Rebekah his wife conceived.
Isaac’s prayer was answered for his wife to conceive of a child. Don’t we imagine that Rebekah herself had been praying for a child? Yet, the Lord was pleased to answer Isaac’s prayer for his wife. In fact, there was a 20 year window between the time these 2 got married and the time that twins (Jacob and Esau) were born to them. Jacob, no doubt, prayed fervently and effectively for his wife Rebekah. And the Lord answered his prayers.
We have every reason to expect that He would answer ours, too, which we offer by faith through Christ.
