I Thessalonians 5:17 says that we should "Pray without ceasing." A very short verse but one that has a terrific challenge. It does not appear that this is just a "ho Hum" kind of challenge but one that requires strong action.
My ESV Study Bible suggests "a mental attitude of prayerfullness, continual fellowship with God, and consciousness of being in his presence throughout each day." Wow! I need to work on this.
Do you realize God has to answer our prayers? He has no option. He cannot refuse. Read Matthew 18:19. But we have to do our part - we have to pray. If your "prayers' are hollow, hurried, kind of "oh by the way ..." - that's not what He is looking for. Read Acts 12:5 - 17.
The scripture above is one of the funniest stories in the bible. It really is, from start to finish. But does show you that God hears us when we are earnest in our prayers.
Max Lucado in his book Outlive Your Life, asks, when is the last time you were on your knees, begging, cajoling, pleading, pounding your fists on the floor, even shaking your fist toward heaven, confessing and reconfessing every sin and reciting God's promises as if God needed to be reminded. "Our passionate prayers move the heart of God" says Max. I really need to look at my "ho hum" prayer life!
