As Christians, though we've been called and chosen out of the world, we still live among different people with different cultures. Sometimes, some Christians find themselves caught in a conflict between their ethnic cultures and their Christian faith. First, it's important to understand that being born again, your primary culture is now in Christ Jesus. You're first and foremost a Christian. 2 Corinthians 5:17 says if any man be in Christ, he is a new creation; you don't have another nature, or belong to another culture; your primary culture is Christ. The Word of God is what guides your way of life and principles. Therefore, you're not an American Christian, African Christian, British Christian, etc. You're a Christian. "Does this mean you can't identify with, or participate in any "cultural" ceremonies in your country, region, or town of natural birth?" Well, such "sub-cultures" or cultural events must not be contrary to the Word of God. They're okay as long as they don't imply anything that's against your faith in Christ Jesus, or your primary culture in Christ! When the Word of God takes residence in your heart and gains the mastery in your life, you'll no longer derive any delight or satisfaction from any culture that's at variance with the Word. The Word will choose your new norms, and become your reference point in life. You'll naturally participate only in those things that don't contradict what the Kingdom stands for, what you have, and who you are in Christ, and God's Word for your life.
