Fellowship is spending time with God and other believers over the Word of God.
I encourage you to find a church that teaches the Bible verse by verse. Ask two questions:
1. Do you teach the Bible verse by verse? They should be teaching the congregation verse by verse most every time they meet.
2. When is the rapture of the church to take place? The answer is that it can happen at any time now.
Call around in your neighborhood, city, county or wherever is close to you and ask these questions of the pastor. One of my favorite churches is Calvary Chapel.
