But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible. – Matthew 19:26

I address some man, so far ungodly that he has no hope of salvation, yet still is anxious to be saved. Perhaps he says, “How can I ever become a Christian? How can I have a new heart and a right spirit?” Is the Spirit of the Lord straitened? Cannot He give you the tenderness you desire? Cannot He give you the desire that seems to be lacking? Cannot He give you faith in Christ, at this very moment? Cannot He breathe into you now that breath of spiritual life that shall make you a living soul, looking up to the cross, and finding life in the Crucified? I pray you, dear friend, if you are under a horrible sense of sin, if you think yourself the worst wretch that ever poisoned the air, if you feel unfit to live as well as unfit to die; yet believe that the Holy Ghost can renew you, and can turn the sinner into a saint, and make you to glorify God even now, this instant. If not, you limit the power of the Holy Ghost; and I come to you with this question, “Is the Spirit of the Lord straitened?” The case is desperate, if it were not for the divine hand; it is beyond all hope, if there were no God. There is no balm in Gilead; there is no physician there; if there had been, the health of the daughter of God’s people would long ago have been recovered. Where, then, is the balm? Look upward for it. Where is the physician? Look upward for Him. There is the Christ of God, “mighty to save,” and there is the living Father Himself, and there is the almighty Spirit. Oh, that you would no longer be filled with suspicions as to the power of God! for with God all things are possible. “Is anything too hard for the Lord?” Is the Lord’s arm waxed short? Trust thou that He can do all things, and do all things for thee whether thou art a saint or a sinner.~ C.H. Spurgeon
