As christians we are known as children of light, and walk in the fruit of Gods spirit of goodness, righteousness, and truth (Ephesians 5:8-17). 8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:9 (For the fruit of the Spirit is in all goodness and righteousness and truth;)10 Proving what is acceptable unto the Lord.11 And have no fellowship with the unfruitful works of darkness, but rather reprove them.12 For it is a shame even to speak of those things which are done of them in secret.13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.15 See then that ye walk circumspectly, not as fools, but as wise,16 Redeeming the time, because the days are evil.17 Wherefore be ye not unwise, but understanding what the will of the Lord is.
God led the people through the wilderness out of Egypt and was the pillar of fire of a cloud by day, and at night He was a pillar of fire to give them light! (Exodus 13:18-22).
From the very beginning the glory of Gods light has led many out of darkness, and we are instructed not to hide our light under a bushel, but to put it on a candlestick so others may see the light of Christ which shines within you(Luke 11:33-36).
Christ within us is the life giving spirit which shines a candle searching all that is within. Revelation teaches us that unless we repent of our sin our candlestick will be removed!(Revelation 2:1-5),(Proverbs 20:27).
