When someone says to you "Let's go to church", what does that mean to you? Does it mean go to a building where there are people of similar beliefs? Does it mean to send your children to Sunday school? Does it involve listening to a sennon? For most of my Christian walk, all of the above was how I defined church.
Now when someone says to me "Let's go to church", they are saying to me: "Let's sit down and study the Word of God. Let's get together and find out more about Jesus." I do not look at going to church as something possible - as I do not need to go anywhere. Jesus said:
"Wherever two or more are gathered together in my name, there I will be also" He is saying that the "church" is not a building, but a time together with Him, and two or more people. You need fellowship and Him - that's all. No building, no pastor, no tithes, no music, no programs, no sermon. Nothing but two people and Jesus. He is the Word of God, and He wants us to learn more of Him. He even said that He would teach us. He sent His Holy Spirit to guide our understanding of Him. As we study the Word, we study the Truths of the Word.
Over the years, a Sunday "service" has come to consist of 3 to 4 main parts. First, there is the worship. That usually consists mainly of scripted music, led by a ''worship team". Next is the sermon. It is usually given by the ''pastor''. Hopefully, the sermon expounds on the Bible, but in many churches it is what is on the mind of the pastor - and that might not be God's Word. In some churches, there is a time of prayer. Unfortunately, though, it is usually one person praying on behalf of the entire 'church'. Collections are taken to support buildings and salaries.
Now contrast that with the Church of God that meets in homes. In most home churches there might, and there might not be, a time of worship. If there is, though, it is more than singing. It would consist of all that God says about worshipping Him. Then there is a time of studying His Word. That might be led by a teacher, or by more than one person, but always under the guidance of the Holy Spirit. The learning of the Word would consist of a time for questions and answers. There is time of fellowship that would consist of food taken together. Most often, there is a time of prayer. Awareness is made, and offerings are taken, for the poor, the widows, the orphans. Home churches also help those that are involved in God's work and have a need; although most teachers, pastors, and preachers have a secular job in addition to their calling.
In order to start a fellowship which meets in your home, invite fellow Christians over and study what God would have you to do. It is all in His Word. Read it.
Through reading the Word of God, He has revealed that the Church Of God:
...... should be a place to learn about Jesus. He walked the face of the earth for thirty-three years and He was the "Word made flesh". In other words, He was the Word of God, walking around. He gave Himself to us. He taught his disciples. He lived what He taught. We need to study Him and learn all we can so we can be like Him; and live like He wants us to. We need to learn of the laws of God and how He wants us to behave. We need to be able to discern the troth from false teachings. We need to be able to discern the false teachers among us .
...... is a gathering of believers. Unbelievers need to become born-again, before coming to God's Church. Therefore, we need to be obedient to God and preach the Good News, outside of the church, so that those that are not believers will come to know Him .
...... should be a place to be filled with God's Holy Spirit. When Jesus left this earth as the "living" Word of God, He said He would send another to be with us. We need the Holy Spirit to help us understand the Bible. We do not need scholars, writers, thinkers, or theologians to understand God. We need His Holy Spirit.
When God baptizes us in His Holy Spirit, we need to use the gifts He has given us. If we have the gift of speaking in tongues, we need to honor and give praise to God by not stifling this gift. Whatever gift God has given us, He has given it to us to use for His glory.
