'Complete' in the Bible

It is the bridegroom who gets the bride, yet the bridegroom's friend, who merely stands by and listens for him, is overjoyed to hear the bridegroom's voice. That's why this joy of mine is now complete.

"But I have a greater testimony than John's, because the actions that the Father has given me to complete the very actions that I am doing testify on my behalf that the Father has sent me.

I've told you this, so that my joy may be in you, and that your joy may be complete.

So far you haven't asked for anything in my name. Keep asking and you will receive, so that your joy may be complete."

"And now I am coming to you, and I say these things in the world so that they may have my joy made complete in themselves.
