When Paul came amongst the Corinthians, he wanted to know nothing "except Jesus Christ and him crucified" (1 Cor 2:2). Knowing Jesus, right in front of people, is enormously freeing and invigorating, and we're convinced that we lack nothing as we do.
Further, knowing He was crucified reminds us that no one needs to die for sin because, in Him, we already have. That changes our approach to people because we see them through the eyes of faith in Christ Jesus. We're not pretending! We're living by faith in Christ. We believe He’s right about what He has done to and for people, and that's reality.
