Galatians 1:16 (NIV)
Reveal His Son in me.
The marvel of the second coming of Christ is not just that He is revealed to us but that He is revealed in us. This is probably the most extraordinary revelation to believers when the Lord reappears. The life of Christ that was sown in us by the Holy Spirit following our repentance, baptism, and rebirth finally grows into the complete manhood of the Son of God when He reappears. The Lord will recognize every resurrected saint on His second coming because He'll recognize Himself in us. Then, when we see Him, we'll be just like Him (1 John 3:2). That is the greatest mystery of the gospel, that Christ is replicating Himself in all of us.
