But, now, instead of saying renewed for good works (as in Eph. 2:10) and thus stating a direct opposite of the evil "practices" of the old man, Paul goes deeper and says: "constantly renewed for epignosis in accord with his Creator." For out of this true, spiritual knowledge arise all true spiritual good works.
"Woe is me, that I sojourn in Mesech, that I dwell in the tents of Kedar." — Psalm 120:5
As a Christian you have to live in the midst of an ungodly world, and it is of little use for you to cry "Woe is me." Jesus did not pray O that you should be taken out of the world, and what He did not pray for you need not desire. Better far in the Lord's strength to meet the difficulty, and glorify Him in it. The enemy is ever on the watch to detect inconsistency in your conduct; be therefore very holy. Remember that the eyes of all are upon you, and that more is expected from you than from other men.
