How appropriate to read this verse as we are approaching Christmas and our celebration of the birth of Christ:
4 For, for this intent have we written these things, that they may know that we knew of Christ, and we had a hope of his glory many hundred years before his coming; and not only we ourselves had a hope of his glory, but also all the holy prophets which were before us.
Hundreds of years before His birth, people were anxiously awaiting His coming. They knew of Him and gloried in Him, even before He came to Earth. How much more should we glory in His life and His love because we know of His words and His works.
