What? Obeying a commandment brings joy? But that’s crazy! (So the world thinks.)
If you obey my commandments, you will remain in my love, just as I have obeyed my Father’s commandments and remain in his love. I have told you these things so that my joy may be in you, and your joy may be complete.
Jn 15.10-11 NET
Jesus gives us his commandments in order to bring us joy. The immediate context of verse 11, “these things” he has told them — or, possibly, this — is the obedience to the commandments. (This stands first in the Greek sentence and thus is emphasized.)
There is no conflict between obedience to the commandments and joy. In fact, it is obedience which brings us Christ’s joy. There is no complete joy without complete obedience.
That’s why Christ’s joy which he gives us is not the same as the world’s joy. The world thinks happiness is freedom from restraint, lack of commitments or obligations.
Christ’s burden is light, the commandments of God not difficult to obey. In them we find our joy and our victory.
