We shall take up the v.4 first:”Behold, I have given him for a witness to the people, a leader and commander to the people.” Prophet Isaiah is referring here to the Messiah who is the everlasting sign. Testimony of Jesus Christ is what we are at present concerned with; who also has another qualification as the covenant for the people. It was of whom we read in the Mount Sinai episode. God himself wrote the second stone tablet to replace the one which was broken. Second set of tablets were to be chiseled by Moses (man). God tells him, “…Hew thee two tables of stone like unto the first…” Who wrote them but God, of course. “… And I will write upon these” (Ex.34:1) Same words on the second as before.
The eternal word is the constitution of God ( “The Word was with God”). It is eternally settled in heaven (Ps.119:89). The Spirit in setting narratives from God the Father and God, the Son does not lose their significance even when both are put together. This three fold cord in scriptural exegesis sets the divine Will and its fulfilment with symbolic values placed at appropriate places presents unity. It is coherent its spiritual significance adding to the understanding of man. It is how God the Spirit glorifies the Word.”He shall glorify me: for he shall receive of mine, and shall shew unto you (John.16:14). In the preceding verse we have the testimony of Jesus that the Spirit shall not speak of himself. From these it is abundantly clear that it is about Jesus Christ we need look at, as a rest frame against which everything else shall find its place.
So the Bible as a narrative is true to the will of God. Secondly glorifying God in terms of the Son places the eternal word as Alpha and Omega in terms of the Son of man. (He is the firstborn of all creation and first born from the dead.) Thirdly symbolic underpinning makes the narrative vivid. Vivid in the sense it is as though it is tagged as natural to its place but amplifying any passage when placed together. Such concordance in ideas is not coincidental but inspired by the Spirit. For example Rock or stone is a tag for Jesus Christ. He was a stone of stumbling ( “And a stone of stumbling, and a rock of offence, even to them which stumble at the word, being disobedient:(1 Pe.2:8)” ) In the case of stone tables it fits the context. Considering the Word was made flesh the symbol of fleshly tables add to the spiritual significance. Now consider another example where St Paul refers Christ to the rock (“And did all drink the same spiritual drink: for they drank of that spiritual Rock that followed them: and that Rock was Christ (1 Co:10:4)”. Does this not connect him nicely with ‘the living waters (John.7:38)’? “He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water. When Prophet Isaiah under inspiration of God writes ‘Ho, every one that thirsteth, come ye to the waters(Is.55:1)’ there is a sense of inevitability as though the symbol was foreordained. It is indeed the case. Isaiah did not make it up but symbol found him. With such symbols of rock, water the Spirit has tagged the role of Jesus Christ in the scriptural narrative. According to the context every passage is set in place as envisaged in Core Will of God. No where else you shall find the Scripture as inerrant and as the book of life than the Bible.
The Word of God is compared to a double edged sword. Let us consider the rider on the white horse, the Lord of Lords and the King of Kings. He is called the Word of God. Out of his mouth goes a sharp sword to smite the nations (Re.19:15). Compare this with what Prophet Isaiah says, | So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it (v.11)”. When nations are judged it shall be according to the word of God and their punishment shall be just; so is judgment of individuals it is on the basis of the eternal word.
Ho, every one that thirsteth, come ye to the waters, and he that hath no money; come ye, buy, and eat; yea, come, buy wine and milk without money and without price.
2 Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness.
3 Incline your ear, and come unto me: hear, and your soul shall live; and I will make an everlasting covenant with you, even the sure mercies of David.
4 Behold, I have given him for a witness to the people, a leader and commander to the people.
5 Behold, thou shalt call a nation that thou knowest not, and nations that knew not thee shall run unto thee because of the Lord thy God, and for the Holy One of Israel; for he hath glorified thee.
6 Seek ye the Lord while he may be found, call ye upon him while he is near:
7 Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the Lord, and he will have mercy upon him; and to our God, for he will abundantly pardon.
8 For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord.
9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
10 For as the rain cometh down, and the snow from heaven, and returneth not thither, but watereth the earth, and maketh it bring forth and bud, that it may give seed to the sower, and bread to the eater:
11 So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
12 For ye shall go out with joy, and be led forth with peace: the mountains and the hills shall break forth before you into singing, and all the trees of the field shall clap their hands.
13 Instead of the thorn shall come up the fir tree, and instead of the brier shall come up the myrtle tree: and it shall be to the Lord for a name, for an everlasting sign that shall not be cut off.
