To cover or not?

Jam 4:17 KJV - Therefore to him that knoweth to do good, and doeth [it] not, to him it is sin. This is why I believe I should wear a head covering. I believe God is pleased with it. It is my outward symbol that I want to be obedient to the LORD and and submissive to His will. Some people in my family are confused about this, but I would like you to know that I am still saved by the Grace of God whether or not I wear the covering; I will still go to Heaven. I do not believe you can lose you salvation for any reason as long as you are truly saved.
