I will come and heal him - Εγω ελθων θεραπευσω αυτον, I am coming, and will heal him. This saying is worthy of observation. Jesus did not positively say, I will came and heal him; this could not have been strictly true, because our Lord healed him without going to the house: and the issue shows that the words ought to be taken in the most literal sense: thus understood, they contained a promise which it seems none of them distinctly comprehended. Foreseeing the exercise of the centurion's faith, he promises that while he is coming, ere he arrives at the house, he will heal him, and this was literally done, Matthew 8:13. There is much beauty in this passage.

I will.

Christ Repressing Rash Discipleship
'And a certain scribe came, and said unto Him, Master, I will follow Thee whithersoever Thou goest. 20. And Jesus saith unto him, The foxes have holes, and the birds of the air have nests; but the Son of Man hath not where to lay His head.'--MATT. viii. 19-20. Our Lord was just on the point of leaving Capernaum for the other side of the lake. His intended departure from the city, in which He had spent so long a time, and wrought so many miracles, produced precisely opposite effects on two of the …

Heaven and Hell
To-night, I shall, I hope, encourage you to seek the road to heaven. I shall also have to utter some very sharp things concerning the end of the lost in the pit of hell. Upon both these subjects I will try and speak, as God helps me. But, I beseech you, as you love your souls, weigh right and wrong this night; see whether what I say be the truth of God. If it be not, reject it utterly, and cast it away; but if it is, at your peril disregard it; for, as you shall answer before God, the great Judge …

Twenty-Seventh Day. Activity in Duty.
"I must work the works of Him that sent me, while it is day; the night cometh, when no man can work."--John, ix. 4. How constant and unremitting was Jesus in the service of His Heavenly Father! "He rose a great while before day;" and, when His secret communion was over, His public work began. It mattered not to Him where He was: whether on the bosom of the deep, or a mountain slope--in the desert, or at a well-side--the "gracious words" ever "proceeded out of His mouth." We find, on one touching …
