Mr. Muller was never actually reckless of his bodily health. His habits were temperate and wholesome, but no man could be so completely wrapped up in his Master's will and work without being correspondingly forgetful of his physical frame. There are not a few, even among God's saints, whose bodily weaknesses and distresses so engross them that their sole business seems to be to nurse the body, keep it alive and promote its comfort. As Dr. Watts would have said, this is living "at a poor dying rate." When the year 1838 opened, the weakness and distress in the head still afflicted Mr. Muller. The symptoms were as bad as ever, and it particularly tried him that they were attended by a tendency to irritability of temper, and even by a sort of satanic feeling wholly foreign to him at other times. He was often reminded that he was by nature a child of wrath even as others, and that, as a child of God, he could stand against the wiles of the devil only by putting on the whole armour of God. The pavilion of God is the saint's place of rest; the panoply of God is his coat of mail. Grace does not at once remove or overcome all tendencies to evil, but, if not _eradicated,_ they are _counteracted_ by the Spirit's wondrous working. Peter found that so long as his eye was on His Master he could walk on the water. There is always a tendency to sink, and a holy walk with God, that defies the tendency downward, is a divine art that can neither be learned nor practised except so long as we keep 'looking unto Jesus': that look of faith counteracts the natural tendency to sink, so long as it holds the soul closely to Him. This man of God felt his risk, and, sore as this trial was to him, he prayed not so much for its removal as that he might be kept from any open dishonour to the name of the Lord, beseeching God that he might rather die than ever bring on Him reproach. Mr. Muller's journal is not only a record of his outer life of consecrated labour and its expansion, but it is a mirror of his inner life and its growth. It is an encouragement to all other saints to find that this growth was, like their own, in spite of many and formidable hindrances, over which only grace could triumph. Side by side with glimpses of habitual conscientiousness and joy in God, we have revelations of times of coldness and despondency. It is a wholesome lesson in holy living that we find this man setting himself to the deliberate task of _cultivating obedience and gratitude;_ by the culture of obedience growing in knowledge and strength, and by the culture of gratitude growing in thankfulness and love. Weakness and coldness are not hopeless states: they have their divine remedies which strengthen and warm the whole being.
