Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing! (Rev. 5:12)
The Lamb of God is the ancient name given to Jesus Christ, and recorded in the Scriptures. More than just a title, it has influenced Christian iconography from the first centuries until today. The image of the Lamb of God has also developed throughout the Church’s history.
