Believing is more than an acknowledgement that something is true. When we believe something, we act on it. Our behavior makes what we believe evident to others. Originally, the kings of Israel were meant to be role models. Their personal relationship with God was a living testimony to the truth of God’s promises. The prophets of Israel were mouthpieces of God, designed to keep Israel’s kings in check, but false prophets undermined the people’s trust and caused Israel to veer off course. By the time Isaiah came on the scene, the role of a prophet was merely to communicate God’s will and pronounce judgment.

Israel’s Messiah was a prophet as well as their king. It was important for these two roles to be combined so that the people could see the alignment between words and actions. In essence, what Jesus did was speak the word of God and simultaneously act it out. His words and behavior were completely consistent. Although we don’t think of Jesus as a believer, he was a true believer in every sense of the word. What Jesus demonstrated was perfect obedience to the will of God at the cost of his own life.

Isaiah described Israel’s Messiah as a servant, one who was called by God, subject to the will and command of his master (5650). In his description of the Messiah’s calling, Isaiah proclaimed, “The LORD hath called me from the womb; from the bowels of my mother hath he made mention of my name, and he hath made my mouth like a sharp sword; in the shadow of his hand hath he hid me, and made me a polished shaft; in his quiver hath he hid me; and said unto me, Thou art my servant, O Israel, in whom I will be glorified” (Isaiah 49:1-3). As an instrument of death, the Messiah was destined to convict the world of its sin. Not only would he cause Israel to repent, but the Messiah would also make it possible for the Gentiles to be saved (Isaiah 49:6).

As God’s chosen people, the Israelites had an advantage over the rest of the world. Through their birthright, they were guaranteed salvation. The main purpose of God’s work was to bring the Israelites to the point of believing. Isaiah provided a clear picture of the Messiah’s obedience in order to convince God’s people that their Savior had come. Approximately 700 years before Jesus was born, Isaiah proclaimed, “The Lord GOD hath opened mine ear, and I was not rebellious, neither turned away back. I gave my back to the smiters, and my cheeks to them that plucked off the hair: I hid not my face from shame and spitting. For the Lord GOD will help me; therefore shall I not be confounded: therefore have I set my face like flint, and I know that I shall not be ashamed” (Isaiah 50:5-7).

At the core of Israel’s believing was the issue of death and eternal life. Jesus willingly went to the cross because he believed God would raise him from the dead (Matthew 17:23). Repeatedly, God delivered Israel from her enemies in the Promised Land, but salvation was ultimately about defeating death itself. Isaiah exclaimed, “Lift up your eyes to the heavens, and look upon the earth beneath: for the heavens shall vanish away like smoke, and the earth shall wax old like a garment, and they that dwell therein shall die in like manner: but my salvation shall be for ever, and my righteousness shall not be abolished” (Isaiah 51:6).

Isaiah likened death to being a prisoner and living in darkness (Isaiah 42:7, 49:9). In contrast, Isaiah portrayed life after death as waking up from sleep. He stated, “Awake, awake; put on thy strength, O Zion; put on thy beautiful garments, O Jerusalem, the holy city…shake thyself from the dust; arise, and sit down, O Jerusalem” (Isaiah 52:1-2). The Messiah’s resurrection from the dead was more than just a restoration of life. The transformation that occurred during Jesus’ resurrection was a supernatural changing from one life form to another. He was no longer a mortal being, but the immortal Son of God.

God’s message of salvation was in many ways news that was too good to be true. Regarding the Messiah, Isaiah asked, “Who hath believed our report? and to whom is the arm of the LORD revealed?” (Isaiah 53:1). The Hebrew word translated believed, aman is the same word used in Genesis 15:6 where it says of Abraham, “he believed in the LORD.” “The meaning here is that Abram was full of trust and confidence in God…It was not primarily in God’s words that he believed, but in God himself…In other words, Abram came to experience a personal relationship to God rather than in impersonal relationship with his promises” (539). Isaiah referred to believing as having a personal relationship to the Messiah, Jesus Christ.

Isaiah predicted the rejection of Israel’s Messiah and made it clear that Jesus would suffer because of Israel’s unbelief. Isaiah declared:

He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not. Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid  on him the iniquity of us all. He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before his shearers is dumb, so he openeth not his mouth. (Isaiah 53:3-7)

In exchange for giving up his life, the Messiah would be rewarded by God with the spoils of his victory. Isaiah foretold of Jesus, “Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bore the sin of many, and made intercession for the transgressors” (Isaiah 53:12). Although the nation of Israel as a whole rejected its Messiah, there were some who believed in Jesus. Isaiah described those who would believe and receive salvation as a wife of youth, and said, “For a small moment have I forsaken thee; but with great mercies will I gather thee. In a little wrath I hid my face from thee for a moment; but with everlasting kindness will I have mercy on thee, saith the LORD thy redeemer” (Isaiah 54:6-7).

Similarities between the Messiah and his followers were noted by Isaiah in his use of the same Hebrew word to designate the servant and servants of the LORD. True believers would be expected to submit themselves to the will of God as the Messiah did. To those who responded in faith, God promised, “No weapon formed against thee shall prosper; and every tongue that shall rise against thee in judgment thou shalt condemn” (Isaiah 54:17). Essentially, the believer was guaranteed entrance into heaven where he would be united with other believers and receive eternal blessings from God (Isaiah 54:11-17).

Isaiah’s great invitation of salvation had two characteristics that made it difficult to resist. First, salvation was free of cost. Isaiah stated, “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” (Isaiah 55:1). Second, salvation was obtained by merely paying attention to what God said. Isaiah declared, “Hear, and your soul shall live” (Isaiah 55:3). The type of hearing Isaiah referred to involved not only the ears, but also the heart (8085). God wanted his people to listen to him using spiritual discernment.

According to Isaiah, the key to believing was an understanding of the ways of God. As much as God had done to develop a relationship with the people of Israel, his effort was fruitless because they couldn’t comprehend his loving nature. Isaiah declared, “For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts” (Isaiah 55:8-9). In order to close the gap, God would himself become the messenger and for the first time since the garden of Eden, he would speak face to face with his children. John the apostle stated it this way. “And the word was made flesh, and dwelt among us” (John 1:14).
