Praying always with all prayer and supplication in the Spirit… – Ephesians 6:18

I fully believe that the darkest time of any true Christian church is just the period when it ought to have the most hope; for when the Lord has allowed us to spin ourselves out till there is no more strength in us, then it is that He will come to our rescue…Look to the Most High, and not to man, or ministers, or modes, or methods, but only to Him, and the guidance of His Spirit…In His name I ask you, can anything be too hard for the Lord? Perhaps in your sphere of service you have grown so dispirited that you are inclined to say, “I may as well give up all further effort; no good will result from my endeavors.” But what have you told the Master, and what have you sought at His hand? Have you told Him all your discouragements? Have you asked Him to speak with power, and has He refused you? If so, then give it up, but not till then, for He can even now “say to the north, Give up; and to the south, Keep not back;” and as when He said to the thick primaeval darkness, “Let there be light,” and the light leaped into being, and the darkness fled, so can He, amid the gross darkness of our huge city, or the not less dense darkness of our villages, create light to our astonishment and to His glory. It is the King’s word we want-nothing short of it, and nothing more. We must get that by prayer; we must wait upon Him with importunity. If there be only two or three whose hearts break over the desolations of the church, if we have only half a dozen that resolve to give the Lord no rest till He establish and make Jerusalem a praise in the earth, we shall see great things yet. ~ C.H. Spurgeon
