The Lord Jesus told us in Matthew 5 that we are the salt of the earth and the light of the world. The function of salt is to kill corrupting elements so that things may be preserved. There is much corruption on the earth today. Everywhere you go you can see the germs of corruption. How we need the salt! And the basic element of the salt is nothing but the humanity of Jesus. The humanity of Jesus in our daily walk is the heavenly salt. The more we live by the humanity of Jesus, the more salty we will be. With this humanity there is the killing power for all the corrupting germs. The more we apply, experience, and live by the humanity of Jesus, the more we will be the salt to this corrupted and corrupting generation. Hence, we see what a responsibility we have. It is not just a matter of shouting, “Jesus is Lord!” but of being the salt with the salting power. We all need the real transformation that comes from the application of the humanity of Jesus in our daily walk.
We have these five matters to practice: calling on the Lord, breathing in the Scriptures, having the Body life, exercising our spirit, and realizing the Lord Jesus within our spirit. This reveals the concept of the apostle Paul. We can enjoy the humanity of Jesus simply by these five things. We have to call on the Lord, we must breathe in the Word, and we must do these things in a Body way in the church life. For this we have such a strengthening factor in our spirit. The Lord Jesus, who is the real humanity, is in our spirit. By exercising our spirit to call on Him and to breathe in the Word in a corporate way, we simply enjoy His humanity.
