It is my conviction that every Christian should be an active member of a Bible-teaching local church. As believers in Christ, we are members of His body and must discipline ourselves to be actively involved in ministry as a way of life. Here are some specific reasons why you should be a committed member of a solid, Bible-teaching local church.
You follow the pattern set forth in the New Testament. Although the word “membership” itself is not used in the New Testament, the principle is present nonetheless. For example, most of our New Testament books are letters that were written to specific groups of people who had chosen to identify themselves with Christ and each other. The word “church” is almost always used to refer to a specific group of people who in some way had committed themselves to serving the Lord and one another in the same ministry location. Numbers were known (Acts 1:15, 2:41, 4:4), rolls were kept (1 Timothy 5:9), servants were selected (Acts 6:2-5), discipline was practiced (1 Corinthians 5:12-13), worship was corporate (1 Corinthians 14:23), and shepherds knew for whom they were responsible (Hebrews 13:17). If you are a part of the body of Christ by virtue of repentant faith in Jesus Christ then you should want to make that association visibly known through church membership.
You have a greater opportunity to use your spiritual gifts. At the moment of your conversion the Holy Spirit came to live inside of your body (1 Corinthians 6:19). When He did this, He brought along the spiritual gift(s) that He sovereignly chose for you to possess for the blessing of the church (1 Corinthians 12:7, 11). As we use our gifts, we are being good stewards of the manifold grace of God (1 Peter 4:10). Can you use your spiritual gift without joining a church? Yes, but in most churches many ministry opportunities are limited to church members only. This is as it should be. Unity in doctrine, purity of life, and submissive accountability to one another and leaders are necessary for a healthy Christian life. The process of becoming a member also gives the existing leadership the opportunity to discern one’s agreement in doctrine, ministry purpose, and goals; thus enabling them to know where best you may serve.
