I am sorry about the experience that you had with the person at your Bible Study. I am a Christian also and it is not fair to kick anyone out of a Bible Study. Being Greek is not a sin in itself--our personal lifestyle choices can become sinful if we make the wrong ones. I am pledging a sorority right now and I refuse to drink or sleep with anyone, and no one has any problems with that. I am a leader in my church youth group and am committing my life to ministry through the Arts. If anything, perhaps, I will be a good witness to my sisters. Many people, Greek or not, begin living a destructive lifestyle in college. It's definitely not just Greeks that party. I think that it's wonderful that you have changed your ways and are coming back to God. Just pray about your testimony and be honest in it. The best advice I can give you as a Christian is to line everything you do up with the Word of God. You can't go wrong, and He will be pleased with you. Sometimes in this life, we will be judged by others, even those who claim to be Christians. But we must remember that no one is perfect, including Christians, but we can only control our own behavior and attitudes. I hope that this will encourage you. If you would like, you can email me.
God bless!!!!!!!
