If you look all through the bible, most if not all of the men of women God we look back to for insight had mentors, had teachers, had fellowship with one another. They had people who they received the anointing from like Elisha and Elija or a mentor like Paul was to Timothy. Jesus even needed John to Baptize him. We are suppose to help each other and come together for a cause, a church only facilitates this. Certainly you risk meeting strange, crazy or wrong people but church is a good thing and the bible really doesn't give us the idea that people are supposed to live their life independent of the rest of the body of Christ. We are supposed to be about the great commission, some form or serving in the body of Christ and we need godly mentors and teachers and preachers in our lives who edify us and push us farther, who God can also use to speak to us like he used Paul and the other apostles to edify the body of Christ as they went and preached at the different churches in their time. God told timothy that if he studied the word of God that he would save himself and also those that heard him. There is a place for church and preachers and pastors in the body of Christ. It is far to easy to get off track if you don't come together with other men and women of God who love you and are going in the same direction you are, you'll need the help.
I remember in Acts chapter 1, they had all gathered together to pray and well you remember what happened. That's what churches are for.
When was last time we actually did something for the kingdom? When was the last time we received a word of the Lord from a man or woman of God like the bible teaches? When was the last time we helped save a lost soul? When was the last time we actually physically served in the body of Christ? There are plenty of good honest churches who could use the help and we could use some direction in our lives. How are people supposed to use the gifts of the spirit, how or who are supposed to prophecy to? If we don't believe in church?
