Joh 15:11 I have told you this so that my joy may be in you and that your joy may be complete.
Jesus had great joy in pleasing His Father by living a fruitful life. The purpose of His teaching is to give man an abundant life, not a joyless existence. The commands for His disciples to obey are for their joy. A consecrated life is a joyous and satisfied life as well as God-glorifying life.
