We live in a society that has, by and large, rejected church membership.
I came across this by John R. Muether; “A child without a family is an orphan to be pitied. A man without a country is a refugee to be welcomed. A Christian without a church is, well, a typical American evangelical.” (I suspect this is even more true of Australian evangelicals.)
In “To Be or Not to Be a Church Member”, Wayne Mack writes,
“Being outside the church is being in Satan’s domain. The Bible indicates that Satan is the “god of this world,” whereas the church is the expression of God’s kingdom on earth and is ruled by Christ, not Satan. Those who are in the world (i.e., outside of Christ) are in Satan’s domain and under his authority. Those who are in the church are under Christ’s authority (2 Corinthians 4:4; Ephesians 2:2; I John 5:19). Consequently, because Christ reigns supremely in the local church, it’s a dangerous thing for a believer not to be identified with one. When we function on our own, outside the church, we’re asking to be knocked around by Satan.
Church membership is not an incidental or optional matter for the Christian. Rather, it’s an essential and important aspect of the Christian life. According to Scripture, being a part of a local church brings with it tremendous privileges, and serious responsibilities, that can be fulfilled in no other way.
Just how important is your church? Consider the following:
1. It provides you with daily and weekly fellowship.
2. It warns and encourages you.
3. It helps hold you accountable.
4. It provides communion for you.
5. It challenges you to use your spiritual gifts.
6. It provides a place for those gifts to be exercised.
7. It helps protect you from heresy.
8. It guides you to godly living.
9. It spiritually ministers to your family.
10. It collectively supports Christian causes and missions around the world.
11. It often means the salvation of souls (perhaps even your own).
12. It helps you when you are spiritually, emotionally, physically or financially in need.
13. It is the pillar and ground of the truth in your area.
14. It disciplines you when you develop a sinful lifestyle.
15. It helps bring down racial barriers.
These are just a few of the benefits of belonging to a good local church.
