What did Jesus look like? No one knows. Yes, there have been many pictures painted of men as “models,” but no true picture exists.
Does this mean we can’t understand what he looks like? Until the second coming of Christ, it does. But his spiritual likeness is just as important, isn’t it?
Someone may say, “How can we come to understand his spiritual likeness?” All we need to do is look in the scriptures for the answer.
Isaiah, by the inspiration of God, called him the “Prince of Peace” (Isaiah 9:6). This title is an important aspect of Jesus to those who need salvation. It doesn’t apply to worldly peace. Unless the world obeys the gospel, it will never know peace. It has never known it.
Jesus brings peace with God when someone obeys him. This is what Romans 5:1 teaches: “Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ.” When a person obeys God through an obedient faith, one is made right with God. When that happens a person makes peace with God. The apostle Paul wrote that Jesus is our peace by breaking down the barriers that stood between Jew and Gentile and principally between God and man (Ephesians 2:14).
Isaiah described the Lord Christ as the great peacemaker in the eleventh chapter of the book that bears his name. The inspired prophet wrote that Jesus would bring right-doing which would bring justice (Isaiah 11:4-5). To illustrate the point, Isaiah listed pairs of animals peacefully coexisting even though they had a “predator/prey relationship” in the world. Then Isaiah wrote how that peace will come: “For the earth will be full of the knowledge of the Lord, as the waters cover the sea.” When God’s word reigns in the heart of a person, peace is the result.
Do you see the Prince of Peace, now? Obeying God means we are no longer enemies. There is no longer the dividing wall of sin between us. Those who obey God enjoy a new relationship with him. Have you found peace in your life? Obey the gospel, and you will.
