To summarize Mr. Muller's service we must understand his great secret. Such a life and such a work are the result of one habit more than all else,--daily and frequent communion with God. Unwearied in supplications and intercessions, we have seen how, in every new need and crisis, prayer was the one resort, the prayer of faith. He first satisfied himself that he was in the way of duty; then he fixed his mind upon the unchanging word of promise; then, in the boldness of a suppliant who comes to a throne of grace in the name of Jesus Christ and pleads the assurance of the immutable Promiser, he presented every petition. He was an unwearied intercessor. No delay discouraged him. This is seen particularly in the case of individuals for whose conversion or special guidance into the paths of full obedience he prayed. On his prayer list were the names of some for whom he had besought God, daily, by name, for one, two, three, four, six, ten years before the answer was given. The year just before his death, he told the writer of two parties for whose reconciliation to God he had prayed, day by day, _for over sixty years,_ and who had not as yet to his knowledge turned unto God: and he significantly added, "I have not a doubt that I shall meet them both in heaven; for my Heavenly Father would not lay upon my heart a burden of prayer for them for over threescore years, if He had not concerning them purposes of mercy." This is a sufficient example of his almost unparalleled perseverance and importunity in intercession. However long the delay, he held on, as with both hands clasping the very horns of the altar; and his childlike spirit reasoned simply but confidently, that the very fact of his own spirit being so long drawn out in prayer for one object, and of the Lord's enabling him so to continue patiently and believingly to wait on Him for the blessing, was a promise and prophecy of the answer; and so he waited on, so assured of the ultimate result that he praised God in advance, believing that he had practically received that for which he asked. It is most helpful here to add that one of the parties for whom for so many years he unceasingly prayed has recently died in faith, having received the promises and embraced them and confessed Jesus as his Lord. Just before leaving Bristol with this completed manuscript of Mr. Muller's life, I met a lady, a niece of the man referred to, through whom I received a knowledge of these facts. He had, before his departure, given most unequivocal testimony to his faith and hope in the Saviour of sinners.
