As followers of Jesus we live in light of Grace. We are asked to follow Jesus actively.
Often the focus we hear from others is on how we should not live. It is as if avoiding sin is following Jesus. We must, of course, live in a manner worthy of God, however, living by faith is not simply avoiding sin.
Living by faith is actively following God. Actively being a blessing to others. Living by faith is a courageous boldness that demands that we do.
We must also be holy. But being holy without actively living out our faith is not possible. To be different than the world we must love the world. Unmerited and flowing love is the mark of true Christian living.
