IV.--A LESSON IN GRACE.--Sin may be forgiven and guilt removed, and this to the certain knowledge of the penitent. One of the devil's lies is that either you are too wicked to be saved, or, if saved, you cannot hope to know it in this life; the one drives men to despair, the other prevents enjoyment of salvation. Isaiah knew that his sins were forgiven, and we have yet to learn that the cross of Jesus has made it less possible for us. It was from the altar the coal came that touched the lips. It is still true that it is sacrifice that takes away guilt. We have an altar, a sacrifice, a benediction such as Isaiah never knew for himself; we understand his sayings as he could not. "By His stripes we are healed." Reader, do you long for pardon, for conscious forgiveness? Wait on the Lord! Think of what He suffered, and why He suffered, and you shall sing with joyous lips-- My pardon I claim, For a sinner I am, A sinner believing in Jesu's name. He purchased the grace, Which now I embrace; O Father, thou knowest He hath died in my place. V.--A LESSON IN THEOLOGY.--"I heard the voice of the Lord, saying, 'Whom shall I send? Who will go for us?' What does this mean? Is it bad grammar or good theology? It sounds like "And God said, Let Us make man in our image?" "And the Lord God said, Behold the man is become as one of Us." In John xii, 40, 41, we find that the Son of God, Jesus of Nazareth, was the Lord who spoke the words we read in verses 9 and 10. In Acts xxviii. 25 we are told it was the Holy Ghost who spake by Isaiah. What does this mean but that the Divine Three in One and One in Three was the Lord whom the prophet saw? VI.--A LESSON TO WORKERS.--When iniquity is purged away there is a willingness to be sent on God's errands. The lips that had been touched said, "Here am I, send me." If we are not willing to go, it is because there is still need of cleansing. Let those of us who find our feet slow to move on God's errands come again to the place of burning. We shall do well to say with Charles Wesley, in one of his less known poems-- Ah! woe is me, immerst in sin, A man of lips and life unclean! How shall I with Thy message run, Or preach the pardoning God unknown? Unless my God vouchsafe to cheer His guilty, trembling messenger, My fears disperse, my sins remove, And purge me by the fire of love! O wouldst Thou teach my lips once more, The comfort of Thy grace restore; Assure me, Lord, that mine Thou art, And stamp forgiveness on my heart; Then should I, in my Jesu's name, Glad tidings of great joy proclaim: Of grace, which every soul may find, And glory, bought for all mankind. CHRISTIAN, YOUR GREATEST DIFFICULTIES WILL COME FROM YOUR OWN SIDE. IT WAS NOT PHAROAH WHO KEPT MOSES OUT OF CANAAN. LX. PAUL AT SEA. ACTS xxvii. 22-25.
