This is a quote from Outlive Your Life: You Were Made to Make A Difference by Max Lucado.
Let's pray, first. Traveling to help the hungry? Be sure to bathe your mission in prayer. Working to disentangle the knots of injustice? Pray. Weary of a world of racism and division? So is God. And he would love to talk to you about it.
Let's pray, most. Did God call us to preach without ceasing? Or teach without ceasing? OR have committee meetings without ceasing? Or sing without ceasing? No, but he did call us to "pray without ceasing." (1 Thess 5:17)
Did Jesus declare: My house shall be called a house of study? Fellowship? Music? A house of exposition? A house of activities? No, but he did say, "My house will be called a house of prayer." (Mk 11:17)
No other spiritual activity is guaranteed such results. "When two of you get together on anything at all on earth and make a prayer of it, my Father in heaven goes into action" (Mt 18:19) He is moved by the humble, prayerful heart.
