The biggest problem with our prayers is not that they are too short, but too small. Our biggest sin in prayer is not the infrequency of our petitions, but the finitude of our petitions. Small prayers are fit only for a small God, small prayers blaspheme! Don’t strive to pray more as much as to pray big.
This language is not meant to push you toward using prayer for more health and wealth, but beyond that. Praying big does not mean praying for more measurable stuff, but praying for the infinite. Stuff is measurable, God is not. Also this does not eliminate prayer for daily needs or casting all our anxieties upon Him (I Peter 5:7), but rather establishes the proper setting for such requests.
The Disciple’s Prayer is comprised of six requests that can be divided into two groups of three requests each. The pronouns are your clue to the division. The first three all concern “Your”; not your your, but His Your. The final three concern “us”. The first three are worshipful longings, the last three are needs humbly requested.
So prayer is to begin with God. Prayer will reveal our priorities. What you pray for (content) is what you pray for (motive). That is, what you request in prayer, is why you pray. The first petition reveals what should be first in our hearts, the glory and renown of God. If this isn’t first, your prayers are idolatrous. Pray big or sin, these are your options.
Prayer seeks the saving rule and reign of God to come and regenerate men’s hearts so that they hallow His name and so that His will is done on earth as it is in heaven. The answer to our deepest longings in prayer should fall like a mountain thrust to the earth from the heavens totally rearranging the landscape of this world and we are asking only for feathers.
Pray prayers as big as God. Pray prayers for God.
Oh that you would rend the heavens and come down, that the mountains might quake at your presence—as when fire kindles brushwood and the fire causes water to boil— to make your name known to your adversaries, and that the nations might tremble at your presence! When you did awesome things that we did not look for, you came down, the mountains quaked at your presence. From of old no one has heard or perceived by the ear, no eye has seen a God besides you, who acts for those who wait for him. You meet him who joyfully works righteousness, those who remember you in your ways. Behold, you were angry, and we sinned; in our sins we have been a long time, and shall we be saved? – Isaiah 64:1-5
