In his book “Kingdom Disciples,” Dr. Tony Evans points out how major department stores like Saks Fifth Avenue in NYC often have large display windows. In these windows, you will find mannequins that are impeccably dressed based on the season and the fashion being promoted. The reason the owners place these mannequins where they do is to advertise to the general public what their store has to offer, hoping to lure them inside. In other words, these mannequins exist for something greater than themselves, to advertise something bigger than themselves. He uses this as an illustration of how Christian have been saved for a purpose greater than themselves. We’re to showcase the glory of the One who has saved us!
Even so, God saved us not merely for ourselves alone but to serve as His advertising agency of His greater kingdom. His people are to make His kingdom so attractive that observers not only admire them, but are drawn to the kingdom because of how impressive we look and live as its official representatives. This is why our primary concern as disciples of Jesus Christ must be to seek first His kingdom and His righteousness. He hasn’t left us to do this all by ourselves. Rather, His Spirit has come to take up residence in our lives. In John 8:12, Jesus says that He is the Light of the world. In Matthew 5:14, He says that we are the light of the world. We are merely to reflect the light that He has placed within us.
Tony Evans–“A kingdom disciple is a believer who takes part in the spiritual development process of progressively learning to live all of life under the lordship of Jesus Christ.”
