Your belief that Jesus is the messiah -- and that his second coming will fulfil the (actual) messianic prophecies in the Hebrew scriptures -- notwithstanding, there is nothing in Isaiah 9:7 that explicitly prophecies a messiah coming a second time.

How about this:

Isaiah 40:10
Behold, the Lord God will come with strong hand, and his arm shall rule for him: behold, his reward is with him, and his work before him.

To Yet Be Fulfilled in the Person of Jesus Christ at His Second Coming

Revelation
(12) And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be

Isaiah 41:4
Who hath wrought and done it, calling the generations from the beginning? I, the Lord, the first, and with the last; I am he.

Revelation
13) I am Alpha and Omega, the beginning and the end, the first and the last.
