I believe there are four main reasons why Christians should go to church regularly.
The first reason is simply to follow or obey His teachings on gathering together. Matt 18:20 “For where two or three are gathered together in My name, I am there in the midst of them." Even in the Old Testament Israel would meet regularly to hear the Word of God taught and for worship. In the New Testament when the early church was first founded they met every day for fellowship, teaching, worship and communion. Hebrews 10: 25 says, “not forsaking the assembling of ourselves together, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching.”
The second reason is to provide a place to worship together our Lord and Savior. There is something special when many voices rise in unison to give praise to our God and King, singing words of adoration and praise. The words being sung remind us of His power, His love and His ability to carry us through the hard times that we all experience in this life. Also many have already prayed for the moving of His Spirit to meet in the gathering to touch each of our lives with His presence and with joy over the praise being lifted up to Him.
The third reason is to provide a place to give our gifts and or money to help those in need as well to meet the needs of providing a place to meet together so that we may all grow in Christ. (I find that many don’t seem to think about the fact that if no one gives through the church all churches, except small home churches, will stop existing.)
The fourth reason is to learn from gifted individuals that teach and preach His word and then show us how to implement God’s teachings individually as well as corporally. It is in this setting that we have the information to grow and become all the Lord desires us to be. In the first reason I quoted Hebrews 10:25 “not forsaking the assembling of ourselves together, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching.” This is the “what we are not to do.” The verse before gives us the “why.” It says, “v24 and let us consider one another in order to stir up love and good works”. This verse again tells us of our need for one another. The word stir up means to “stir up or provoke. In a good sense, a sharpening; used figuratively meaning an encouragement to some action or feeling.” Very soon after making Adam, God made Eve as a helper and companion. Our Creator knows we need others in our lives to encourage, help and just be there for us. The word translated “church” in the Greek language is ekklesia. This word is made up of two words, ek – out of and klesia – called ones, therefore the meanings is the “called out ones.” Nelson Bible Dictionary says, “This word is used 115 times in the New Testament, mostly in the Book of Acts and the writings of the apostle Paul and the general epistles. At least 92 times this word refers to a local congregation. The other references are to the church general, or all believers everywhere for all ages.” In other words you cannot have church with only one person.
I read something many years ago that said, “Friends divide our sorrows and multiply our joy.” They also “stir up” us to greater heights in our walk with our God.
Let us go back to the original question, “Do Christians need to go to Church”? If they want a real relationship with God they definitely do! Not only for themselves, but also for the others going there.
