We are called to be in the world but not of it. Followers of Christ are somewhat alien to this present evil age; we are citizens of the age to come who, nevertheless, live amidst this present age. Our churches should be reflective of the culture that is to come and thus, counter-cultural to the world around us. As we remain with each other in distinctly Christian ways we are being prepared to reach out with love, grace, maturity, and truth.
Jonathan Leeman is an author, director of 9Marks Ministry, and a member of Capital Hill Baptist Church in Washington, D.C. He writes extensively on what the church should look like so that we reflect the image of God in our remaining with each other. This particular post lists twelve aspects of how the church can be culturally distinct so that we might be culturally engaged.
I want to encourage you to read his excellent blog post:
