This distinction is a real one, viz. between trusting in our feelings and trusting in the Savior, though not very obvious at first, and is highly important in its connection with the religious life. It seems to me, that religious feelings are valuable, and can be valuable, only as they tend, in their ultimate result, to unite us more and more closely to the Divine Mind. If, therefore, we are so unwise as to stop and to rest in our feelings as the ground of our hope, and especially if we take a degree of complacency in them, in themselves considered, or because they may properly be regarded as our own feelings, we not only stop short of God, to whom they should lead us; but pervert them, valuable as they are in their proper exercise and relations, to our own exceeding detriment.
We come to the conclusion, therefore, and repeat again, that we should not place any reliance upon our feelings, in themselves considered, as a ground of acceptance with God; and also that we should not, in any point of view, take any unduly interested and selfish complacency in them. We must banish and crucify this form of idolatry also, which is none the less dangerous for being so interior and secret. If, in the exercise of naked faith, we will turn our eyes to God and to his glory rather than to ourselves, we shall soon experience a divine reaction in the soul itself. And shall find, that God, who is faithful to his promise, will abundantly take care of us both without and within. We shall then have both the right degree and the right kind of feelings. We shall have no idols, but we shall have God; and we shall have no feelings that are appropriate to idols, but shall have the feelings which are appropriate to God. And in accordance with this view, and in point of fact, it will be found that of two Christians, the one, who is the most penitent, the most humble, the most grateful, the most devoted in his love, will think the least of those particular exercises. His mind will be, as it were out of himself. You will see him living religion, and not merely talking or thinking about religion. Such a person will hardly be conscious of his feelings, considered as objects of distinct contemplation and thought: and will know them chiefly in the blessed result of increased oneness with his heavenly Father. He is not destitute of feeling; but his feeling is, if we may so express it, not so much to dwell upon feeling and to trouble himself about feeling, as to lose himself in the will of God. Another mind, viz. "the mind of Christ," may be said to have taken inward possession; and so close is the union, which has now been formed between himself and God, that he finds himself perplexed and at a loss to discover the nature and operations of what he was formerly wont to call his own mind. His state corresponds in a great degree, and perhaps precisely, to what is implied, in the expressions of the Apostle, when he says, Gal. 2:20, "I am crucified with Christ; nevertheless I live; YET NOT I, BUT CHRIST LIVETH IN ME.
