This is a topic that I personally think many people haven't really thought about deeply but probably have some strong opinions on.
While I don't think that I can come up with any accurate numbers to support the claim that many former and active believers have ceased to partake in that once considered mandatory act of attending a weekly service, I believe that it is universally accepted that the church is not presently viewed as the honorable place that it once was.
While church scandal has been around ever since the church had been formed, I believe that it is because of the quick access to information dispersed in cyberspace through social media that has delivered the final knockout blow in the perception that all things officially holy are not what it's all cracked up to be.
Granted, I don't think anyone would say that all churches are riddled with major sex scandals, political power plays and sole intention of merely fleecing the flock, but it's only human nature that will focus on the bad apples that will always gain more attention than the good the church has done and give an "out" to those who never wanted to stop living a sinful life in the first place.
Now matter where you fall on the vast scale of opinion on what the real intentions of the modern day church is all about, it appears to me that the overall integrity of all things church is at an all time low and that many have taken the route of worshipping their God on their own and in their own unique way.This is why many former church members feel a whole lot better NOT going at all as they now don't have to deal with the spiritual speedbumps that are present in the so called houses of worship called the modern day church.
So the question remains, can you still make it to Heaven without ever going to church?
