Along with freedom in Christ comes responsibility. Even though our lives are held by God's grace and love, we have a responsibility to live a life worthy of respect, to set a good example for those around us, especially for non-believers. We are not to "flaunt" God nor His grace as something that protects us or allows us to do whatever we want and then seek forgiveness. Instead, we are to live responsibly, and care for others in ways which cause us to set a good example for them. Sometimes nothing can cause a non-believer to become more firmly entrenched in their non-belief than seeing a believer who behaves no differently than they always have, who does not visibly show their transformation in Christ. If we are living out an attempt to show others the love that Christ showed for us, then that is not a worry.
