And the word of God increased; and the number of the disciples multiplied in Jerusalem greatly… – Acts 6:7

“How is it likely,” says one, “that we can hope to make an impression upon the present age? What means have we but the simple gospel of Jesus Christ?” …My dear brethren, we are weak, but we are not weaker than the first disciples of Christ. Neither were they learned, nor were they the wealthy of the earth: fishermen, the most of them, by no means men of cultivated ability-their tramp was that of a legion that went forth to conquer as well as to fight. Wherever they went and wielded the sword of the Spirit, which is the Word of God, their enemies were put to confusion. It is true they died in the conflict. Some of them were slain by the sword, and others of them were rent in sunder by wild beasts; but in all these things they were more than conquerors through Him that loved him. The primitive church did tell upon its age, and left a seed behind which the whole earth could not destroy; and so shall we by God’s grace if we are equally set upon it, equally filled with the divine life, equally resolved by any means and by all means to spread abroad the savour of Jesus Christ’s name: our weakness shall be our strength, for God shall make it to be the platform upon which the omnipotence of His grace shall be displayed. Keep together, brethren, keep close to Christ; close up your ranks. Heed the battle cry; hold fast the faith; quit yourselves like men in the conflict, and the gates of hell shall not prevail against you. Only may the King Himself lead us onward to the fray, and we shall not fear the result. ~ C.H. Spurgeon
