To be holy is to be “set apart” (sanctified or consecrated) for God’s purposes. Holiness is not a state of mind, but a state of being. Holiness is not walking around in studied piety, noxious goodness or angelic loveliness. It’s not halos or attire. It’s not external, at all. Holiness is a condition of the heart. The “set apart” heart has been broken and is wholly surrendered to the rule of the Lord Jesus Christ and none other.
