Well know that especially when you are a new Christian that satan gets sort of ticked and wants to get you back! Hence your feelings of apprenhension and uncertainty. Hold on girl, and pray and ask God to hug you tighter and keep you under His wing ever tighter. As for this guy, I guess I don’t understand the problem. There is nothing wrong having a Christian friend, male or female. It needs to start there before anything. Who knows, maybe this is someone God has placed in your path to help you during this time and who knows what else. Pray on this my sister in Christ. Listen to what God wants of this situation. God bless and keep you.
