Meditation doth discriminate and characterise a man; by this he may take a measure of his heart, whether it be good or bad; let me allude to that; "For as he thinketh in his heart, so is he." Proverbs 23:7. As the meditation is, such is the man. Meditation is the touchstone of a Christian; it shows what metal he is made of. It is a spiritual index; the index shows what is in the book, so meditation shows what is in the heart.
There are times when life, like a river, is over your head and you feel like you are drowning. Yet, the water from these very rivers wash away your filth. What the water does not remove, the fire purifies.
We know God but as men born blind know the fire: they know that there is such a thing as fire, for they feel it warm them, but what it is they know not. So, that there is a God we know, but what He is we know little, and indeed we can never search Him out to perfection; a finite creature can never fully comprehend that which is infinite.
Take care of giving up your first zeal; beware of cooling in the least degree. Ye were hot and earnest once; be hot and earnest still, and let the fire which once burnt within you still animate you. Be ye still men of might and vigour, men who serve their God with diligence and zeal.
