Besides the fluctuations due to our own changes of mood, there are also the distracting influences of even the duties which God lays upon us. It is hard for a man with the material task of the moment that takes all his powers, to keep a little corner of his heart clear, and to feel that God is there. It is difficult in the clatter of the mill or in the crowds on 'Change, to do our work as for and in remembrance of Christ. It _is_ difficult; but it is possible. Distractions are made distractions by our own folly and weakness. There is nothing that it is our duty to do which an honest attempt to do from the right motive could not convert into a positive help to getting nearer God. It is for us to determine whether the tasks of life, and this intrusive external and material world, shall veil Him from us, or shall reveal Him to us. It is for us to determine whether we shall make our secular avocation and its trials, little and great, a means to get nearer to God, or a means to shut Him out from us, and us from Him. There is nothing but sin incompatible with the fixed heart, the resolved will, the continual communion, nothing incompatible though there may be much that makes it difficult to realise and preserve these. And then, of course, the trials and sorrows which strike us all make this fixed heart hard to keep. It is easy, as I said, to vow, 'I will sing and give praise,' when flesh is comfortable and prosperity is spreading its bright sky over our heads. It is harder to say it when disappointment and bitterness are in the heart, and an empty place there that aches and will never be filled. It is harder for a man to say it when, like this Psalmist, his soul is 'amongst lions' and he 'lies amongst them that are set on fire.' But still, rightly taken, sorrow is the best ladder to God; and there is no such praise as comes from the lips that, if they did not praise, must sob, and that praise because they are beginning to learn that evil, as the world calls it, is the stepping-stone to the highest good. 'My heart is fixed. I will sing and give praise' may be the voice of the mourner as well as of the prosperous and happy. III. Lastly, let me say just a word as to the means by which such a uniform character may be impressed upon our religious experience. There is another psalm where this same phrase is employed with a very important and illuminating addition, in which we read, 'His heart is fixed, trusting in the Lord.' That is the secret of a fixed heart--continuous faith rooted and grounded in Him. This fluttering, changeful, unreliable, emotional nature of mine will be made calm and steadfast by faith, and duties done in the faith of God will bind me to Him; and sorrows borne and joys accepted in the faith of God will be links in the chain that knits Him to me.
