The oil lamp of old time has a flax within made of cotton that when trimmed it's light shined brighter. The smoking flax was carefully trim to cut the black harden remains off. In the awareness to this I find further understanding in scripture that speaks of the lamp as salvation, with direction in our path. The oil is the anointed One that gave us fuel. And the light is the shine of glory in God and His Will. Moses face shined of God glory spoken of in ( II Corinthians 3 ) God promise to trim the smoking flax gently ( Isaiah 42:3 ) We are told throughout scripture to believe in Christ, and walk with Him. Christ did the will of His Father and all was in His Glory.
