John the Baptist declared "Behold the Lamb of God Who Takes Away the Sin of the World." Where did he get the concept of the Lamb of God since the term is not explicitly used in the Old Testament scriptures? This message covers three Old Testament passages that are relevant to this name and likely fed the mind of John so that he declared Jesus to be the "Lamb of God." These three passages were also clearly understood by the New Testament church to apply to Jesus Christ and his sacrifice for our sins.
