"Then Jesus spoke to them again, saying, 'I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.'" John 8:12
Many people mistake knowledge, doctrine, theology and teaching as the light of life. The real light is not mere knowledge. It is none other than the Lord Himself.
May the Lord be merciful to us that by His light He may take away our self-reliance, so that we no longer dare to trust in our own knowledge and judgment. Oh that we may come to Him saying, "Lord, You are the light. In seeing You, I now realize that what I have seen in the past have been but things".
If doctrine is what we preach, doctrine will be received by people; but this is a dead object, not the light of life. If the light of life is what we dispense, it will not only enlighten people's life, it will also be shone through them.
