Another urging to holiness

i cant put in words how much important it is for us, as children of God to live lives that are different from the lives of the people that live in this world!
Everything about us should be different: how we dress even, how we talk, what kind of entertainment we consume, the places where we go to socialize and who we socialize with and also, the kind of celebrations we celebrate,
We can be a powerful example to this dying world and needs so badly LIGHT and Guidance
Bible reference

2 Corinthians 7:1
Therefore, since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.
