If this, then, be the line on which our human nature can alone be developed, if a profound harmony with God be that which can alone give permanence and completeness to our nature, if in accordance with all that we see in the world around us some men fail of attaining the end of their creation, and lie for ever blighted and useless, while others are carried forward to fuller and more satisfying life, we cannot but ask with some anxiety to which class we belong. Good and evil are in the world, happiness and misery, victory and defeat; do not let us deceive ourselves by acting as if there were no difference between these opposites, or as if it mattered little in our case whether we belong to the one side or the other. It matters everything: it is just the difference between eternal life and eternal death. Christ did not come to play with us, and startle us with idle tales. He is the centre and fountain of all truth, and what He says fits in with all we see in the world around us. But in endeavouring to ascertain whether the great change our Lord speaks of has passed upon us, our object must be not so much to ascertain the time and manner of our new birth as its reality. A man may know that he has been born though he is not able to recall, as no man can recall, the circumstances of his birth. Life is the great evidence of birth, natural or spiritual. We may desire to know the time and place of birth for some other reason, but certainly not for this, to make sure we have been born. Of that there is sufficient evidence in the fact of our being alive. And spiritual life quite as certainly implies spiritual birth.
