"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.
Plenty of experiences confirm to us that many who are skillful in creating hot atmosphere know very little of the Lord, many excitable persons are quite lacking in the knowledge of the Lord. Only Christ is life, the rest is not. For life depends not on how enthusiastic is our emotion or on how manifold is our thought; it rests exclusively on whether the Lord has manifested His own self. There is therefore nothing more important than to know the Lord. If we know the Lord as our life, we realize the utter futility of all natural efforts in spiritual matters. Hence we look to Him alone.
Before we were saved, worldly objects and affairs usurped the place of Christ; but after being saved, spiritual objects and affairs now tend to occupy Christ’s place. Hence God must show us one day that “Christ is my world.” Earlier He took from us the things of this world; presently He is taking away our spiritual thing or things. He removes our personal patience, love, power, gentleness, humility. Indeed, He removes all, that we may not live by these good things but live by a Person instead. We are patient not because we have received a power to be so, but because we have got a Person. So is it with humility and the rest: not a power but a Person. It is for this very reason that God engages in a destroying work daily in the lives of His children that He may also do the work of a daily building up. Daily destroy things and daily build up Christ. Brethren, God will take away all things in order to give you one Person who is to be simultaneously your humility, your patience, your gentleness, and your love. For Christ is all. And this is what Christianity actually is.
God's end is Christ, so also God's means is Christ. It is through Christ to Christ. He says He is the bread of life—He does not say He will give us the bread of life. He says He is the way—He does not say He will guide us to walk in the way. He says He is the truth—He does not say He will teach us a truth. He says He is true life—He dos not say He will give us a life. Whatever Christ gives us is His very own self... Christianity is Christ... Christianity is not any one thing which Christ gives to me; Christianity is Christ giving Himself to me. (see John 6:48, 11:25, 14:6)
