John 3:29 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.
How many weddings have you been to where the bridegroom has a trembling or elated voice when trying to say his vows to the bride?
The bridegroom may be the one who is marrying the bride, but the people around him will be able to share in the joy and excitement of the moment because they are there with him.
On some days the bridegroom may sound like he is getting cold feet and may need a bit of encouragement to go forward.
We can share in the joy and excitement of people coming to know Christ by being there with them and encouraging them forward too.
