All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any. I Corinthians 6:12
As Christians we must understand that God provides choice He will never step over our will. What he would like is for our wills to align with His. This being said no its not a sin to where them but doesnt mean its not a stumbling block. Thats where the above scripture comes in.
It is difficult to not follow worldly practices, however, we must be careful in what we imitate. Cologne type was not a good example to use in comparison with image. The physical church must be honest in acknowledging the impact and influence the world has on us. We imitae the world, they appear to disciple us. (Im not just talking about outward adorning). Lets be real if the world wasnt doing it, neither would we. It wouldnt be an issue.
For those individuals who continue to speak of God knowing the heart. Lets look at scripture and discover what God actually says about the heart. Jer 17:9/Ec 9:3 to name a few. A study of proverbs will enrich your understanding of trusting in your own heart. Its foolishness. We dont know our hearts, the LUST OF THE WORLD appeal to our hearts. For this reason God had to give us a new heart. You dont know your heart, stop trying to think you do. God does and He declares its wickedness. Look at the world-- thats the heart of man. If not for the grace of God there we go. This being said. We must remind ourselves of the scripture I John 2:16-17. The world appeals to the flesh. Thats why God says dont love it, sometimes left unchecked your desires fall in line with the very occurrances of the world.
When did it every become do what you want? You may not mean it in this manner, but many take it dont judge (we are living epistles read of men im not judging just reading--) the question may be what are people reading. We will know them by their fruit-time for fruit inspection.
Modesty in all is key. Again I dont say its a sin to wear ear rings, some look nice; but I do know it can be a distraction. We can state its someone elses problem, but lets go to scripture:if eating meat offends --- dont do. Im not saying dont wear them what I am saying is seek God, check your real reasons for wanting to wear them, seek scriptures, the epistles are filled with advice on christian living.
Didnt mean to be this long got carried away. Love God with your HEART< MIND & SOUL.
