There is a huge difference between the old grain of sand believers once were and the salt of the Earth they became, after they were born again, saved, indwelt by and filled with the Holy Spirit. As salt that has its savor, believers are preservatives—preserving others from evil inherent in the souls of mankind that have been corrupted by sin. As “tangy” salt, believers also are moral compasses that influence others to be just/fair, to be merciful, and to be humble. Therefore, it is only after believers have lost their saltiness that their witness becomes ineffective and the distinctions between a follower of Christ and the rest of the world get blurred.
There can be no doubt that the way Christ Jesus uses the word Ekklesia, when He declares to Peter that the Lord would be the foundation upon which Christ Himself would build His Community of believers, is to express His original intent for His Ekklesia. That original intent for His Ekklesia is that the Lord expects every Ekklesia to be a Community of believers—disciples who not only are concerned about the world, from a Christ-like perspective, but also are representing the Kingdom of God on this Earth in such a way that they are causing the entire world to conform to the culture of the Lord’s Ekklesia. In other words, Christ Jesus’ original intent for His Ekklesia is that each Community of called-out believers would be changing the world until everyone in the world begins to walk, talk, and act like true believers in Christ are supposed to walk, talk, and act.
Are we the true salt and the true light? Are we intimately communicating with God? Have we quenched and/or grieved the Holy Spirit? Has our sanctification process stopped?
