TMOTCS: BELIEVERS IN CHRIST AND THE WORLDLY PERSON
When someone is called and is a saved person, his new life becomes different from his former life. He is in Christ and no more in the the world because no man can serve two masters at the same time. He is to start living a new life worthy of christian calling “I urge you to live worthy of the calling you have received” (Eph 4:1). A change has taken place and the new conduct must correspond with the new calling.
The worldly man is not spiritual but mundane. He is worldly-minded and very much concerned with material things. He is sophisticated in things pertaining to this world compared with spiritual things. He is devoted to sensual pleasures of this world and worldly temptations. He is fleshly, earthly, impatient, disobedient, materialistic, selfish, greedy, covetous, naive, profane, avaricious wicked and morally corrupt. So, the worldly person is wise worldly and not worldly-wise.
On the other hand, the believer is to be unworldly, spiritual, immaterial, ethereal, transcendental and not concerned with the temporal world or swayed by mundane considerations. He is to be humble, helpful, selfless, patient, obedient; always behaving decently (Rom 13:13). The believer is the direct opposite of the worldly person because he is in Christ and not in the world. He is full of love, always joyful, walking worthy and staying away from all evil. The redeemed is worldly-wise and not wise worldly.
