God designed humanity to labor in His
presence.
But since the fall, all mankind has been inclined to hide from God and labor independently from Him.
Yet... with the coming of Christ, we are again able to work before God under the blessing of His presence.
To continue to labor apart from God is to build the city of man... a city destined for destruction.
But to do the work of your calling in His presence is to contribute to the everlasting city of God.
