“For a child will be born to us, a son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace. There will be no end to the increase of His government or of peace, on the throne of David and over his kingdom, to establish it and to uphold it with justice and righteousness from then on and forevermore. The zeal of the Lord of hosts will accomplish this.” Isaiah 9:6-7
Did Jesus make a mistake? Is the Bible in error? Is God unable to deliver what He has promised? No. Jesus said, "Peace I leave with you; My peace I give to you; not as the world gives, do I give to you. Let not your heart be troubled, nor let it be fearful" (John 14:27.)
Here's another aspect of Jesus' ministry to mankind - our peace. But how does that peace become ours? Wonderful direction is given in Isaiah 26:3 where it says of God, "The steadfast of mind Thou wilt keep in perfect peace, because he trusts in Thee."
When Christ is our Savior, His peace actually lives in us. That's why the Apostle Paul could say in 2 Thessalonians 3:16, "Now may the Lord of peace Himself continually grant you peace in every circumstance." "And let the peace of Christ rule in your hearts" (Colossians 3:15). In Philippians 4:7 he says, "And the peace of God, which surpasses all comprehension, shall guard your hearts and your minds in Christ Jesus." And in Galatians 5:22: "But the fruit of the Spirit is love, joy, peace, patience..."
How can we have peace? Jesus' own words speak best: "These things I have spoken to you, that in Me you may have peace. In the world you have tribulation, but take courage; I have overcome the world" (John 16:33). Receive His peace.
