The man in this story had accepted the invitation but came without his wedding garment, and when he was asked why he was not properly dressed he had no answer and was thrown out of the celebration. Our garments are our lives, and we must make sure that our garments (lives) are producing fruit and not just having leaves. It is not enough to act like a Christian but God wants us to live what we talk about, if we fail to do so just as he cursed the fig tree in that no one will ever eat from it again, in the end He will tell us to depart from Him, He never knew us!
