When God calls a man by His grace, he cannot but come. You may resist the minister’s call, but you cannot the Spirit’s call. The finger of the blessed Spirit can write upon a heart of stone, as once He wrote His laws upon tables of stone. God’s words are creating words; when He said “Let there be light, there was light”; and when He says, “Let there be faith”, it shall be so. When God called Paul, he answered to the call. “I was not disobedient to the heavenly vision” (Acts xxvi. 19). God rides forth conquering in the chariot of His gospel; He makes the blind eyes see, and the stony heart bleed. If God will call a man, nothing shall lie in the way to hinder; difficulties shall be untied, the powers of hell shall disband. “Who hath resisted his will?” (Rom. ix. 19). God bends the iron sinew, and cuts asunder the gates of brass (Psalm cvii. 16). When the Lord touches a man’s heart by His Spirit, all proud imaginations are brought down, and the fort royal of the will yields to God.
