God cares about the way in which we live. He cares about how we conduct our lives. In fact, we're called to conduct ourselves in a "manner that is worthy of the gospel of Jesus Christ." That is a TALL order! Thankfully, the reality of the gospel means that we don't have to try harder in order to be accepted by God. Instead, in response to His gracious forgiveness, we can seek to consistently live in ways that are worthy of the gospel.
We don't have to be perfect... but we can seek to be consistent!
