Gospel Community

I will put enmity between you and the woman, and between your offspring and her offspring; he shall bruise your head, and you shall bruise his [Jesus'] heel.
Genesis 3:15 (emphasis added)

This verse predicts that one day there will be a group of people who—instead of living as self-seeking individuals whose self-centered desires will ultimately put them at enmity with each other [e.g. Cain and Abel, 2 Corinthians 5:15]—will live as a selfless community whose Christ-centered desires will put them at enmity with Satan instead of each other.

Its fulfillment? Gospel community. The church. The body of Jesus Christ made up of the ransomed from every tribe, language, people and nation (Revelation 5:9-10).

I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. [In other words, watch out for and avoid people who destroy gospel community]. For such persons do not serve our Lord Christ, but their own appetites [their own selfish interests! Which are in direct contrast with gospel community], and by smooth talk and flattery they deceive the hearts of the naïve. For your obedience is known to all, so that I rejoice over you, but I want you to be wise as to what is good and innocent as to what is evil. The God of peace will soon crush Satan under your [the church's] feet. The grace of our Lord Jesus Christ be with you.
Romans 16:17-20 (emphasis added)
