If the door is shut and difficulties hedge the way, God will go before the man He calls, and open the door and sweep away the difficulties (Isaiah xlv. 2, 3).

If others think the man so ignorant and unfit that they doubt his call, God will give him such grace or such power to win souls that they shall have to acknowledge that God has chosen him. It was in this way that God made a whole National Headquarters, from the Commissioner downwards, to know that He had chosen the elevator boy for His work. The boy got scores of his passengers on the elevator saved, and then he was commissioned and sent into the Field to devote all his time to saving men.

The Lord will surely let the man’s comrades and brethren know, as surely as He did the Church at Antioch, when “the Holy Ghost said, Separate Me Barnabas and Saul for the work whereunto I have called them” (Acts xiii. 2).

Sometimes the one who is called will try to hide it in his heart, and then God stirs up some Officer or minister, some Soldier or mother in Israel, to lay a hand on his shoulders, and ask, “Are you not called to the work?” and he finds he cannot hide himself nor escape from the call, any more than could Adam hide himself from God behind the trees of the garden, or Jonah escape God’s call by taking ship for Tarshish.

Happy is the man who does not try to escape, but, though trembling at the mighty responsibility, assumes it, and, with all humility and faithfulness, sets to work by prayer and patient, continuous study of God’s word, to fit himself for God’s work. He will need to prepare himself, for the call to the work is also a call to preparation, continuous preparation of the fullest possible kind.

The man whom God calls cannot safely neglect or despise the call. He will find his mission on earth, his happiness and peace, his power and prosperity, his reward in Heaven, and probably Heaven itself, bound up with that call and dependent upon it. He may run away from it, as did Jonah, and find a waiting ship to favour his flight; but he will also find fierce storms and bellowing seas overtaking him, and big-mouthed fishes of trouble and disaster ready to swallow him.

But if he heeds the call, and cheerfully goes where God appoints, God will go with him; he shall nevermore be left alone. The Holy Spirit will surely accompany him, and he may be one of the happiest men on earth, one of the gladdest creatures in God’s universe.

“Lo, I am with you alway, even unto the end of the world,” said Jesus, as He commissioned His disciples to go to all nations and preach the Gospel. “My presence shall go with thee,” said Jehovah to Moses, when sending him to face Pharaoh and free Israel, and lead them to the Promised Land.

And to the boy Jeremiah, He said, “Be not afraid of their faces: for I am with thee to deliver thee.... And they shall fight against thee; but they shall not prevail against thee; for I am with thee” (Jeremiah i. 8, 19).

I used to read these words with a great and rapturous joy, as I realised by faith that they were also meant for me, and for every man sent of God, and that His blessed presence was with me every time I spoke to the people or dealt with an individual soul, or knelt in prayer with a penitent seeker after God; and I still read them so.
