Not including the examples in the OP, what are the main reasons people do not go to church?
1. Theology - they do not agree with the theology of the church. I live in a small town. The nearest church is about 10 minutes away, but it is Anglican. Too much I don't agree with, especially the "following the world" attitude. The next nearest church is a Mennonite Brethren Church. Another one I don't agree with. Esp. The modern turns it has taken. Skip over a variety of churches, and arrive at my Baptist Church. I like the theology although it is an hour round trip to get their and back. I also like the people, but that is #2. Unless you are 500 miles away from your nearest neighbor, there really is no excuse for not finding a church you agree with. If you can't, it is likely YOUR problem, not the churches.
2. Poor relationship skills. They cannot get along with fellow Christians. it is called "fellowship" because we are to meet with our fellow Christians. As someone said sometimes they use the excuse of "hypocrites" or a multitude of other excuses but basically it comes down to not loving our brothers and sisters in Christ. I think this is a huge reason. If you don't fellowship with other Christians how on earth are you obeying the commands below? I lived out in the country for 15 years, and I made the effort to go into town and fellowship, I can't see what the excuse is.
"This is my commandment, that you love one another as I have loved you.13 Greater love has no one than this, that someone lay down his life for his friends." John 15:12-13
"Whoever says he is in the light and hates his brother is still in darkness. 10 Whoever loves his brother abides in the light, and in him there is no cause for stumbling. 11 But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes." 1 John 2:9-11
3. Sin - people are sinning and do not want to go to church for fear of someone discovering that sin.
I am talking about willful sinning, and the desire to hide it from people. In fact, it is God the person is accountable to, and the conviction felt attending church comes from the Holy Spirit, not from other people.
"The life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us— 3 that which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ." 1 John 1:2-3
"No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him. 7 Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous. 8 Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil. 9 No one born of God makes a practice of sinning, for God's seed abides in him, and he cannot keep on sinning because he has been born of God. 10 By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother." 1 John 3:6-10
Finally, I do know there are people who are housebound. I have been housebound on occasion because of my RA. Like last week and the week before. I could not climb out of bed the pain was so bad. I got emails from people asking how I was doing, and they were worried about me. I am sure someone would have visited if I had asked, but I was not in that state. And God arranged for me to be well enough this Sunday to go to church. If someone is out of fellowship because they are housebound, that is probably a lot on the church for not caring for them.
The moment I got saved, I knew it was God's will that I attend a body of believers for corporate worship. My husband had not gone to church since he had gotten saved, because of some personal issues. I dragged him out the door, and we have gone ever since. And he certainly is happy that I have never stopped encouraging him to attend church, make friends, and be the social butterfly I am. I do feel sorry for those who have depression, anxiety or are unbearably shy, but the more you overcome these things, and attend church, the more like you are to grow into a mature Christian and leave some of those things behind. Just don't use it as an excuse!
PS. God has had to temper my extrovertism quite a bit! But partly that has been my husband, my partner and companion and the other part has been the growth experienced in attending church.
