It is the plan and purpose of God that every one of His servants should enter into an abiding experience of spiritual blessing and service in Jesus Christ.
Isaiah 6:3b: “Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory!”
All vital Christian experience begins with an experience with the Lord Jesus Christ. Isaiah was worshipping in the temple, when, suddenly, he was over-awed with a tremendous sense of the Lord’s presence (vv. 1-5):
This sevenfold vision of the Lord produced in Isaiah a deep humbling and a conviction of sin: “Woe to me! I am ruined!” (v. 5); and the only thing which will produce a consciousness of sin is a vision of the Lord (Job 42:5-6; Luke 5:8; Revelation 1:17). How sinful we see ourselves in the light of His awful purity! We discover, with Isaiah, that sin separates from God, for the word “ruined” should literally read, “cut off” (Isaiah 59: 1-2). Sin separates from God; Matthew 27:46 we have a terrible illustration of the power of sin to separate from God, when He, “who had no sin”, bore this separation for us (2 Corinthians 5:21). What then should we do with our sin?
In v. 5 we read that Isaiah said, “I am a man of unclean lips.” This is the only way to get rid of sin: confess it. It is no good trying to cover it; it must be forsaken (Proverbs 28:13). Notice that Isaiah’s besetting sin had to do with his lips, and when he made his confession to the Lord it was not a general confession, but a particular confession. He did not say, “Woe to me…I am a sinner”; he said, “Woe to me…I am a man of unclean lips.” He confessed to the Lord the particular sin of which he had been convicted. What happens when we do this?
Verses 6-7 suggest:
It is when we confess our sins that the Holy Spirit applies the blood which was shed on Calvary, and we are cleansed (1 John 1:7- 9). God demands clean servants. He cannot use unclean instruments (Isaiah 52:11; 2 Corinthians 7:1). If we confess our sin to the Lord, we enjoy that intimate communion with Him which makes it possible for us to hear His voice.
Verse 8: “I heard the voice of the Lord” but notice that Isaiah only heard the Lord after he had experienced the cleansing. God is wanting men and women whom He can commission and equip to go forth in His Name to preach His Word among the nations. Why do not more hear Him saying, “Whom shall I send, and who will go for Us?”? Is it because of sin in the lives of God’s people? What comes next?
Verse 8: when Isaiah became conscious of the Lord’s need of a man he did two things:
It is vitally important to notice that in this matter of dedication the Lord wants US before He wants our service. He wants both, but first it must be, “Here am I” – and then, “Send me!” Then what?
“He said, Go and tell this people” (v. 9). Now we can see why God wanted to cleanse Isaiah’s lips; it was because He wanted him to go and tell. How wonderful that the sinning “member”, when cleansed by the Lord, is the “member” He will use for His glory! (Romans 6: 13). Notice to whom Isaiah had to go: the people amongst whom he dwelt. Wherever you or I may be, it is just there that the Lord wants us to witness for Him. Fullness of blessing is to be doing God’s will in the place of His choosing.
