"I have told you this so that my joy may be in you and your joy may be complete. ‘ (John 15:11) What Jesus discussed was 'the Parable of the Grapevine'. The subject was: When we are in Christ's love, our joy will then be complete. Jesus pointed out that the principle of “complete joy” was by way of living out the true meaning of love. “Do to others whatever you would have them do to you. “ (Matt 7:12) “If someone has offended you seven times in a day, and returns to you seven times saying, “I repent, you should forgive him.” (Luke 17:4) In order to love, one must learn to lay low: Humble oneself. And at the same time maintain the heartfelt relationship with God: Through prayers. “Martha, Martha, you are anxious and worried about many things. There is need of only one thing.” (Luke 10:41) When we always open up our hearts for the needs of our neighbors, God’s grace will flow in deep down of our hearts.
