The next condition of prevailing prayer, is--_obedience to the light_. Now, what does it mean to walk in obedience? Well, it does _not_ mean, searching this New Testament to find out how little of God's grace will get you into Heaven! It does not mean, running round to see what this person says and the other person says about such and such a text, in order that you may escape from the real, practical meaning of the text! Such people are hypocrites at heart, whoever they are; or at least, insincere. They don't want to know God's will; they would much rather not know it. They want to get away from the plain, practical, common-sense meaning of the text, and then they say, "It doesn't mean exactly what it says," and "It should be interpreted so-and-so;" and they stroke themselves down, and try to make themselves feel comfortable when they are traitors at heart. _That is not walking in the light_. Walking in the light is like walking in the sun--not running behind a pillar there, and a tree yonder, to get away from the light. It is coming right out, and saying, "Now, Lord Jesus; I want to know Thy will. Lord, pour Thy light upon me. I am prepared to follow it, even though it is to the block and to the stake." First, desire to have the light. Oh! it makes my heart ache--I was going to say boil--with righteous indignation, in jealousy for God's honor, to think that He should be so traduced and blasphemed by those who profess to love Him--who try to make out that they get wrong for want of light. Nothing of the kind. Here is plenty of light; but you must say, "Yes, Lord, I am willing to have it, even if it condemns me. If it condemns my heart, my head, Lord, pour it on me. If it condemns my life, pour it on me. If it condemns those companions, those indulgences, pour it on me: I will give them up. If it condemns my business, pour it on me: I will abandon such business, and sooner die in the workhouse than continue in it. If it condemns my family relations, I will come out from them, and follow Thee." The Lord will always answer such a soul as that. He will put His finger down on this sore spot and the other, and He will tell you what to do, and you will be as sure of it as if you heard His audible voice. What does it mean to walk in the light? Obey His voice. Don't stop to confer with flesh and blood, but, as Paul did, get up, and set off to commence the career which your Master commands. Paul did not stop to confer with flesh and blood. He did not stop to reckon what it would cost him, but on he went, and never stops, until he reaches the block. _That_ is walking in the light--obeying--not standing, quibbling with the Lord about it; not saying, "Oh! but,"--but _doing_ it.
