Lk 2:28, 32, Jn 1:9-12, Jn 8:12, Jn 9:5, Jn 12:36
In the Old Testament, God commanded the priests to light a lamp in the tabernacle and keep it from being extinguished. Without a lamp in the tabernacle, the priests could not perform their duties. (Lev 24:3)
Lev 24:3 Without the vail of the testimony, in the tabernacle of the congregation, shall Aaron order it from the evening unto the morning before the Lord continually: it shall be a statute for ever in your generations.
Jesus is the light to the Gentiles and the glory of Israel. (Luke 2:28,32)
Luke 2:28 Then took he him up in his arms, and blessed God, and said, 32 A light to lighten the Gentiles, and the glory of thy people Israel.
Jesus is the light of the world, the light of life. (John 1:9-12, John 8:12, John 9:5)
John 1:9 That was the true Light, which lighteth every man that cometh into the world. 10 He was in the world, and the world was made by him, and the world knew him not. 11 He came unto his own, and his own received him not. 12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
John 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
John 9:5 As long as I am in the world, I am the light of the world.
If we believe in Jesus as the Christ, we become sons of light. (John 12:36)
John 12:36 While ye have light, believe in the light, that ye may be the children of light. These things spake Jesus, and departed, and did hide himself from them.
