1. Wonderful Counselor. The one word serves to qualify the other—he is a wonder of a counselor.
“Wonderful” is a word that primarily describes the LORD or extraordinary or supernatural things in the Scriptures; it means “extraordinary, surpassing, marvelous, wonderful.” It was not used in a trivial sense, as we often use the English word “wonderful.”
Genesis 18 the LORD announced the birth of Isaac to the aging Abraham and Sarah. When Sarah laughed in her heart, the LORD, knowing she laughed, said, “Is anything too hard for the LORD?” “Hard” is our word—Is anything too marvelous, wonderful, extraordinary, for the LORD?
Wonder is Strongs #6382 pele, masculine noun
Hard is Strongs #6381 pala, denominative verb from pele
David, meditating on the knowledge of the LORD, came to realize that the LORD knows everything about him, his thoughts, his intentions, even the words he is trying to say, all of it
Psalm 139:1-6
1 You have searched me, Lord,
and you know me.
2 You know when I sit and when I rise;
you perceive my thoughts from afar.
3 You discern my going out and my lying down;
you are familiar with all my ways.
4 Before a word is on my tongue
you, Lord, know it completely.
5 You hem me in behind and before,
and you lay your hand upon me.
6 Such knowledge is too wonderful (6383 - from the same as pele) for me,
too lofty for me to attain.
When the Angel of the Lord (Christophany) appeared to Manoah (Judges 13), he asked Jesus, "What is your name...". Jesus replied, 'Why do you ask my name? It is beyond understanding/wonderful (6383)"
“Counselor" is the second word in the title. The word means “one who plans.” It means he has the wisdom to rule. Isaiah 11:2 will explain that this king, this Immanuel, has the Spirit of Counsel, that is, his wisdom to rule is God-given. This work of our Lord continues today, for when He went away He promised to send another counselor (John 14:16), the Holy Spirit, who would continue to counsel by His Word, to convict, to teach, and to transform people. What made Jesus such a wonderful counselor? He knew what was in man (John 2:25). He had that wonderful knowledge of which David spoke.
2. The Mighty God. Not only was Messiah to be wonderful in counsel, he was to be the image of God as no other was. Isaiah just announced in chapters 7 and 8 that this king would be known as ‘Immanu-’el, “God with us.” To say “a king is with us” would be of little effect. But to say that a king is coming whose power will display that God is with the people—that is a sign. According to John 8:58 He identified Himself as the great I AM of the Old Testament, the sovereign Lord God of Israel. In Matthew 24:30 he announced, “All power is given to me.” “I AM”—”all power.” In sum, Jesus is the Mighty God...who came in the flesh.
3. The Everlasting Father. The third title in many ways is the most striking. It is literally “father of perpetuity,” that is, one who will be perpetually the father. Jesus is the “Son” who is given is also known as the Father. Jesus said, “I am not of this world” (John 8:23), “I came in My Father’s name” (John 5:43), and finally, “I and the Father are one” (John 10:30).45 So Jesus is the expressed image of the Father, the Sovereign king-maker. By taking this title, Everlasting Father, the Messiah is to be known as the One who is the sovereign Lord over the ever changing years—he produces and directs eternity.46 Such a name belongs to a god, not just any divine creature or spiritual being, but to the God.
4. The Prince of Peace. This last title means that the Messiah will be one who ensures for his people the blessings of peace. He will be a prince who brings peace. In Judges 6:24 because of the greeting of “peace” from the Angel of the LORD the place was called “The LORD is peace.” Whenever the LORD visited his people, whether by the Angel of the LORD or by His promised Messiah, it was to announce or promise peace to the world (Isa. 11:6-9; Ps. 72:3,7). Jesus brought peace with God through redemption by His death and resurrection, and will eventually bring total peace through His exalted reign over all the earth.
