For followers of Jesus, unity is one of the primary values. Maintaining unity has utmost importance. We need to behave in ways that maximize peaceful relationships. We need to be humble, patient, and gentle with each other.
But he also made us individuals. He created us to do god. He gave individuals to equip God’s family to complete these good things. As God’s family serves each other as individuals, and as members of the family, the family grows. The whole family attains Christ’s image. We will speak truth to one another, motivated by love. So, we will all grow into His image. He gives grace, so all parts grow and builds the body, as each one fills his purpose.
He gives grace that powers the growth. But the growth will not come if each part does not do its job.
