"If thou knewest the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee living water." John 4:10

We cannot know the nature, though we may know the necessity, of the gift of God, till we experience its power as revealed and shed abroad in our soul. Then we know some measure of the gift of God when we feel eternal life flowing through our spiritual veins. How do I know I live naturally? Is not my participation of natural life known to me by an internal consciousness that I possess it? I know I live, because I feel that I live. And so, if we have spiritual life, there will be, at times and seasons, an internal consciousness that we have it; we shall feel the spiritual heart beat, and the spiritual lungs breathe, and the spiritual eyes see, and the spiritual ears hear: in a word, we shall be internally conscious of those emotions and sensations which are peculiar to the life of God in the soul. Spiritual life will be seen in its own light, felt in its own power, and shine forth in its own testimony. The little that we do know (and it is indeed for the most part but a little) makes us long for more of it.

If ever we have received "the gift of God" into our conscience; if ever we have felt the mysterious operation of divine life in our hearts; if ever we have known the sweet emotions and peculiar sensations by which it manifests itself, it has killed us to all other religions; and as a measure of divine life has flowed into the heart out of the fulness of the Son of God, we want no other religion but that which stands in the power of God; by that alone we can live, and by that alone we feel that we can die.
