In Eph. 4:11-16, Paul gives us a reason to attend church. He says that God gave us evangelists, pastors, and so on in order to equip "the saints for the work of ministry, for the edifying of the body of Christ." When I am by myself, reading the word or other good books, I am not really edifying someone else. I am getting a lot of knowledge, but I am not living like Christ and going out to others.
God gave us gifts of ministers to teach us to minister. I grew up as a loner. I know what it is to be shut in with my books and TV. I stay the same person. But I changed when I went to a small fellowship where you couldn't help but bump into the same people over and over. Then I began learning things I couldn't get in the books or the Internet. If you do not interact with others, then you won't know what I'm talking about. It is easy to talk to others on the Internet than to have the courage to go up to strangers and talk to them.
I am deaf, so it is doubly hard. But I find more grace when I do the impossible and go against myself and go out to people. It is just not the same on the Internet. It is too safe here. Go out to the people. Talk to someone you've never met before. Share a verse or a thought with the person next to you. Be a vessel the Lord can use next time you visit.
You are not too small. You are not so great a sinner that the Lord can't cleanse you and use you. Don't think you don't have it in you to minister to others. All of us have to start somewhere. Listen carefully and respond to the message you hear. Speak it to the person next to you and ask for their opinion. Share again and see where it leads.
