Psalms 51:10

Purge me with hyssop, with the blood of Christ applied to my soul by a lively faith, as the water of purification was sprinkled with a bunch of hyssop. The blood of Christ is called the blood of sprinkling, He 12:24. If this blood of Christ, which cleanses from all sin, cleanse us from our sin, then we shall be clean indeed, He 10:2. He asks not to be comforted, till he is first cleansed; if sin, the bitter root of sorrow, be taken away, he can pray in faith, Let me have a well-grounded peace, of thy creating, so that the bones broken by convictions may rejoice, may be comforted. Hide thy face from my sins; blot out all mine iniquities out of thy book; blot them out, as a cloud is blotted out and dispelled by the beams of the sun. And the believer desires renewal to holiness as much as the joy of salvation. David now saw, more than ever, what an unclean heart he had, and sadly laments it; but he sees it is not in his own power to amend it, and therefore begs God would create in him a clean heart. When the sinner feels this change is necessary, and reads the promise of God to that purpose, he begins to ask it. He knew he had by his sin grieved the Holy Spirit, and provoked him to withdraw. This he dreads more than anything. He prays that Divine comforts may be restored to him. When we give ourselves cause to doubt our interest in salvation, how can we expect the joy of it? This had made him weak; he prays, I am ready to fall, either into sin or into despair, therefore uphold me with thy Spirit. Thy Spirit is a free Spirit, a free Agent himself, working freely. And the more cheerful we are in our duty, the more constant we shall be to it. What is this but the liberty wherewith Christ makes his people free, which is contrasted with the yoke of bondage? Ga 5:1. It is the Spirit of adoption spoken to the heart. Those to whom God is the God of salvation, he will deliver from guilt; for the salvation he is the God of, is salvation from sin. We may therefore plead with him, Lord, thou art the God of my salvation, therefore deliver me from the dominion of sin. And when the lips are opened, what should they speak but the praises of God for his forgiving mercy?

Create. What! has sin so destroyed us, that the Creator must be called in again? What ruin then doth evil work among mankind! Create in me. I, in my outward fabric, still exist; but I am empty, desert, void. Come, then, and let thy power be seen in a new creation within my old fallen self. Thou didst make a man in the world at first; Lord, make a new man in me! A clean heart. In the seventh verse he asked to be clean; now he seeks a heart suitable to that cleanliness; but he does not say, "Make my old heart clean; " he is too experienced in the hopelessness of the old nature. He would have the old man buried as a dead thing, and a new creation brought in to fill its place. None but God can create either a new heart or a new earth. Salvation is a marvellous display of supreme power; the work in us as much as that for us is wholly of Omnipotence. The affections must be rectified first, or all our nature will go amiss. The heart is the rudder of the soul, and till the Lord take it in hand we steer in a false and foul way. O Lord, thou who didst once make me, be pleased to new make me, and in my most secret parts renew me. Renew a right spirit within me. It was there once, Lord, put it there again. The law on my heart has become like an inscription hard to read: new write it, gracious Maker. Remove the evil as I have entreated thee; but, O replace it with good, lest into my swept, empty, and garnished heart, from which the devil has gone out for a while, seven other spirits more wicked than the first should enter and dwell. The two sentences make a complete prayer. Create what is not there at all; renew that which is there, but in a sadly feeble state.
