“He will glorify me, because he will take from what is mine and declare it to you.” (John 16:14) What Jesus preaches all comes from the heavenly Father, because “Everything that the Father has is mine.” (John 16:15) “He will not speak on his own, but he will speak what he hears.” (John 16:13) We all are the children of the heavenly Father, therefore the integration of mankind is the final destiny. “They may all be one, as you, Father, are in me and I in you, that they also may be in us, that the world may believe that you sent me. And I have given them the glory you gave me, so that they may be one, as we are one.” (John 17:21-22) It is not difficult to understand what Jesus demands from us, “So be perfect, just as your heavenly Father is perfect.” However, Jesus also gives us the consolation, “For human beings this is impossible, but for God all things are possible.” The salvation of mankind depends on whether we can tie in God’s holy will like the relation of the Holy Trinity, with mutual love and no distinction. Moreover we need to love the world and protect the nature. Humankind or better said, the harmony of the world is all based on mutual co-ordination and acceptance. This is the essence of living out the Holy Trinity.
