Behold, the lamb of God.

 A t his baptism the Holy Spirit filled Jesus with the power to be 'a light to the nations'. Living His life in purity, truth, humility, love, faithfulness and obedience to His Father, Jesus reflected God's light into a sinful world, dispelling the darkness of sin, unbelief and ignorance. He brought us the light of faith and true knowledge so we could know the Father and do His will. The Spirit filled Jesus with the power to offer His life in sacrifice for the sins of the world. John1:29 says of Jesus: 'Behold, the Lamb of God, who takes away the sin of the world!'. As God's Chosen One, faithful and obedient, Jesus 'baptizes with the Holy Spirit' so that the Spirit will give believers the power to be light to the world and to bring God's salvation to the ends of the earth. We are light to the world as we live our lives in 'compassion, kindness, lowliness, meekness, and patience' (Col. 3:12). These virtues dispel the darkness around us just as a lamp placed on a stand 'gives light to all in the house' (Matt. 5:15). We bring God's salvation to the ends of the earth as we seek to live righteous and holy lives, rejecting the temptations that assail us, repenting of the sins we have committed, 'forbearing one another and, if one has a complaint against another, forgiving each other' (Col.3:13). By being light to the nations and bringing God's salvation to the ends of the earth, Jesus glorified His Father: 'You are my servant, Israel, in whom I will be glorified' (Isa. 49:3). Like Jesus, we give glory to the Father by being light to the world and pursuing righteousness and peace. Ask the Spirit to fill you with power so that you may be light to the world and bring God's salvation - mercy, love, peace and forgiveness - to those around you. (excerpt: catholic-bible-school.org)
