Then came the word of the Lord to Isaiah, saying, Go, and say to Hezekiah, Thus saith the Lord, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will add unto thy days fifteen years. And I will deliver thee and this city out of the hand of the king of Assyria: and I will defend this city.
Suddenly, a hand touched me, which made me tremble on my knees and on the palms of my hands. And he said to me, “O Daniel, man greatly beloved, understand the words that I speak to you, and stand upright, for I have now been sent to you.” While he was speaking this word to me, I stood trembling. Then he said to me, “Do not fear, Daniel, for from the first day that you set your heart to understand, and to humble yourself before your God, your words were heard; and I have come because of your words. But the prince of the kingdom of Persia withstood me twenty-one days; and behold, Michael, one of the chief princes, came to help me, for I had been left alone there with the kings of Persia. 14 Now I have come to make you understand what will happen to your people in the latter days, for the vision refers to many days yet to come.”
And the Lord said, I have surely seen the affliction of my people which are in Egypt, and have heard their cry by reason of their taskmasters; for I know their sorrows; And I am come down to deliver them out of the hand of the Egyptians, and to bring them up out of that land unto a good land and a large, unto a land flowing with milk and honey; unto the place of the Canaanites, and the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites.
I randomly picked these three passages from scripture to show that prayer is effective. It took me a long time to realize that while these stories seem special because they are in the Bible and I’ve read them all my life they were not momentous at the time. If we could travel back in time I think we would see that nothing special appeared to be happening. The lesson is that while it may seem that we live in relatively less miraculous times compared to the Bible we have every reason to expect God to do such things in our day. These stories are relevant because they are examples of what is happening even now. And so we should be encouraged to faithfully worship and pray to the Lord for all things.
God changed the course of nations at the prayers of His faithful people. We also have the teachings of Jesus that instruct us to pray according to His will and expect God to answer. The Lord can change the course of our nation, for good, as He had done for many other nations and kingdoms in the past. We can be sure that praying for the gospel to be preached in this country with fruitful results is in accord with God’s will. God delivered nations on the prayers of only one righteous man, which Paul tells us availeth much. How much more so if millions of faithful followers are doing the same. Have no doubts that your prayers matter a great deal.
