Our lives as followers of Jesus is to be different, but not merely otherworldly. We are to be good citizens. We are to add value to our neighborhoods. We are to bless our friends. We are to attach our hearts to the hope of the life of the world to come. But this is not to be at the expense of living life fully engaged in this world.
It doesn't have to be heroic. But we are called to be faithful in common ordinary ways...to the praise of God and the blessing of our neighbor, and in anticipation of being able to give witness to God's love for us and for all people in Jesus.
