I recommend this excellent book and it's free

From "The Simple/House Church Revolution" Book by Roger Thoman . The entire book can still be downloaded here.
I appreciate Rogers attempts to redefine the Church and her mission and doing it for free. Who does that these days? Thanks to Roger and Simple House Church for doing this for us. Also, at the end of this excerpt from the book I offer some thoughts on disciple-making. I am overall very impressed with this work.

"Church according to Miriam-Webster’s online dictionary:
1: a building for public and especially Christian worship
2: the clergy or officialdom of a religious body
3: a body or organization of religious believers: as a: the whole body of Christians b: denomination c: congregation
4: a public divine worship

Webster defines church according to the way this word is used today. I was taught this same definition as a little boy when I would put my hands together and recite the rhyme: “Here is the church, and here is the steeple; open the door and here are all the people.”

Jesus, however, introduced the term “church” with a very different meaning in mind. He used a word “ekklesia” that simply described a group or assembly of people. This is the original definition of the word. He described “church” as those people who were following Him—people walking in allegiance to him. People. His followers. Nothing more than that.

Jesus did not spend much time describing how to organize his people together or how to do meetings. Rather, his focus was on a lifestyle of loving others and obeying Him: “Go into all the world…” “Let your light shine…” “Do what you see the Father doing…” “Love one another…” Church, as defined by Jesus, was simply his followers living life for and with him.

Over the years, however, the word “church” began to include the many structures and forms that we added to the original meaning:
• Public meeting places (buildings or storefronts)
• Organizations of believers who get together to be led by a worship team and preached to by a pastor
• Denominations that we join

But, as John Eldredge reminds us:
Church is not a building. Church is not an event that takes place on Sundays. I know, it's how we've come to think of it. ‘I go to First Baptist.’ ‘We are members of St. Luke's.’ ‘Is it time to go to church?’ Much to our surprise, that is not how the Bible uses the term. Not at all. No. Not at all. Church is God’s people—those who are choosing to live life with Jesus… 24/7. That is it. Nothing more.

But don’t God’s people gather together? Yes. We do see gatherings take place in Scripture. Many gatherings. Most often informal and simple. Normally in homes (Romans 16:5). Everyone participated (1 Corinthians 14:26). They functioned as spiritual families that cared deeply for one another (Romans 12:10). Yet the focus of the church (God’s people) was a lifestyle of Jesus-following, rather than organizing events, attending programs, or joining organizations.

Perhaps the best way to describe the church of the New Testament is as small, vibrant, caring families of believers who are loving others and reproducing themselves into every corner of the world."

The Planter: This is a refreshing book, full of Truth! The author places far too much emphasis on House Churches, in my opinion. How we meet is not the important thing, we can meet as the Body anywhere. The heart of Jesus and His mission is the important thing. I appreciate the fact that he makes claim that all believers should make disciples, but he leaves out bringing new believers through a deliberate consecration/deliverance from sin process. Let me explain, Jesus came to set the captives free and in our disciple making movement here in St. Louis we insist that every believer be taken through a consecration process that leads to deliverance from sin, bondage, strongholds, open doors, demonic activity and the lies of the enemy are replaced with the Truth of God's Word. We have discovered (it took me long enough to see, too long) that without a consecration/deliverance emphasis the new follower isn't totally free to be victorious and nor is he/she Holy Spirit empowered. For us, this is the main thing in disciple making. Now that we have done this our new disciple makers having gone through a consecration/deliverance process are now leading their new disciples through the same. It is part of our disciple making culture.

In the end, we don't just have disciples who profess Christ, we have consecrated disciples who have victory over sin, strong accountability and Holy Spirit power in their lives. This is the really cool part. With the consecration element of our discipleship process we have solid Christ followers who obey Jesus regardless of the cost. Becoming a disciple of Jesus is not reduced to saying a sinners prayer but more about being totally consecrated to Him.
