We, as Christians, have created an image of what holiness looks like that's unbelievable. We expect truly holy people to be saintly and perfect. How many of
those people do you find in the Bible? Other than Christ, the ones chosen to do God's work are human and carry their fair share of flaws and frailties.
Holiness is not knowledge, great professions, doing many works, zeal for religious matters, morality and respectability nor keeping company with Godly people. It is being of one mind with God, ever seeking His wisdom and direction. It includes kindness, generosity, mercy and humility. It takes much work and practice but by the Grace of God, it is there for us all!
