To some "worldliness" is what and how you look externally...or it's watching TV or listening to certain songs. To me this seems so profound...worldliness is an ATTITUDE. You can never watch TV, never listen to secular music...dress to the "T" according to some church standards...and still be a worldly person, because it's about ATTITUDE.
The world fights. The world hates. The world condemns. The world divides. The world......Look at American politics and how divided they are...because they are of the world...now look at the church and how divided it is.....see...standards are just a mask...and sadly standards can mask a worldly heart.
Everyone sees the outward and judges...
Mat 23:25 "Woe to you, scribes and Pharisees, hypocrites! For you clean the outside of the cup and the plate, but inside they are full of greed and self-indulgence.
Mat 23:26 You blind Pharisee! First clean the inside of the cup and the plate, that the outside also may be clean.
Mat 23:27 "Woe to you, scribes and Pharisees, hypocrites! For you are like whitewashed tombs, which outwardly appear beautiful, but within are full of dead people's bones and all uncleanness.
Mat 23:28 So you also outwardly appear righteous to others, but within you are full of hypocrisy and lawlessness.
2Co 5:12 We are not commending ourselves to you again but giving you cause to boast about us, so that you may be able to answer those who boast about outward appearance and not about what is in the heart.
Rom 2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
Rom 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
Holiness Standards can become about outward show just as much as it was meant to de-emphasize the outward person.
1Pe 3:3 Do not let your adorning be external--the braiding of hair and the putting on of gold jewelry, or the clothing you wear--
1Pe 3:4 but let your adorning be the hidden person of the heart with the imperishable beauty of a gentle and quiet spirit, which in God's sight is very precious.
1Pe 3:5 For this is how the holy women who hoped in God used to adorn themselves, by submitting to their own husbands,
For some they measure themselves by themselves and by others to feel Holy and believe themselves to be not worldly while ignoring their own attitudes of the heart
