The Scriptural answer is very simple, but it goes deep. If a man would have spiritual power with men, and prevail, he must be real with his Lord. What he says, he must first know, he must first live. As regards HIM who is at once his Master and his Gospel, he must indeed "_know_ whom he has believed," [2 Tim. i. 10.] and, in calm but entire simplicity, "_submit himself_ under His hands." Granted a true creed, and a humble faith in its Subject, he must, in quiet reality, "yield himself unto God," if he would be used by Him. Observe the Apostle's phrase; "Yield yourselves," [Greek: parastÍsate heautous]: not, "yield to God" (though that is implied), but, "yield _yourselves_, hand yourselves over, to God," as you would hand over a tool, a weapon [Rom. vi. 13.]. And another aspect of the same thing appears in the same Apostle's later words: "_If a man_ _purge himself_ of these, he _shall be a vessel_ unto honour, sanctified (to), and meet for, the Master's use," [Greek: hÍgiasmenon euchrÍston tÙ DespotÍ]. [2 Tim. ii. 21.] The deepest secret of spiritual power, in God's sense of the phrase, lies there. Let the man be watchful over his Scriptural creed, and let him discipline his life, and let him toil in his study, and among his people. None of these things can be spared; they are all vital. But the central secret, which they as it were enclose and protect, lies in the words _Surrender in faith_. And the Christian man's heart must be its own inquisitor, before God, in the inquiry after the point, or points, where you, where I, need to make that surrender for ourselves. In the void thus left, in the chasm thus cut deep into our ambitions, into our self-love, the mighty Spirit in His tranquil fulness will spring up. And then, whether we know it or not, we Ministers of the Word shall assuredly be vehicles of spiritual power, to our Lord's praise. * * * * * FAREWELL. So let me close these fragmentary words spoken "to my younger Brethren." May God's mercy be upon the writer. Upon the readers, whom he loves in the Lord, may grace and peace come every hour and day, in secret, in society, in holy ministration of Word and Ordinance. And in due time, when they are no longer juniors but, if the Lord will, veterans and leaders in the work, may they in turn pass on the message to those who follow, in the name of Jesus Christ. Amen.
