In my opinion, what John the Baptizer said of himself in comparison to Jesus Christ should be shared by all children of God,
“He who has the bride is the bridegroom; but the friend of the bridegroom, who stands and hears him, rejoices greatly because of the bridegroom’s voice. Therefore this joy of mine is fulfilled. He must increase, but I must decrease” (John 3:29-30).
It did not bother John that Jesus was becoming more popular. John was happy to decrease as Jesus increased.
