On our own all we do is useless but when we work with God and follow his guidance everything we do is usefull. God enables us to do amazing things and when we glorify Him, He makes us look amazing, He builds up our reputation. We need to do what is right in God's eyes even if we think it is at the expense of our reputation, if we trust God, He will honour us, and lift us up, both in His eyes and in the eyes of those around us.
