Unity is the greatest indicator that a church community will last a long time and be fruitful, not money, talent, or even growth. When the church is united under the gospel and in Jesus, it is strong, resilient, and effective.• Unity means commitment, not necessarily conformity—staying together even when we disagree• Paul uses language of mending torn fabric when he calls for unity in the Corinthian church• True commitment involves time, sacrifice, consistency, and contentment• Division occurs when we allow our differences to define us rather than our common faith in Christ• The Corinthians were dividing themselves by following different leaders—Paul, Apollos, Cephas• Our favorite teachers are wrong about something, and everyone has something to teach us• We should practice curiosity with each other rather than flattening people with labels• The cross has power to unite us because it teaches two unchanging truths: we are sinners in need of grace, and Jesus died to save sinners• Unlike worldly communities that dissolve when circumstances change, Christ's church is built on eternal truths
