Well, I have little doubt about it any more. The church in this country, is changing. One reason is that the general perception of Sundays is changing. For those who do attend "church" it is more about connecting and seeing friends, checking in with accountability, getting a rush from the worship team, or other things, than it is about really paying attention to the preaching, deliberately offering up awe and affection to the Lord. I have fended off this feeling for a long time. Now, I think this is the main interest of American Christians. At least the evangelical ones.
It isn't that we have apostasized from our core doctrines or abandoned our love of the Word of God. We just love ourselves more. That's my opinion, at the moment at least.
Ideally, I wish all Christians would do these things:
Commit to attending a church every week, even if things aren't ideal there. Make time for worship. He is worth it.
Be loyal to whatever church you go to, for as long as you can do so. And demonstrate that loyalty in many ways.
Read your Bibles every day.
Forgive your fellow church people heavily, and frequently.
Ask God to make you less about you and more about other people. Ask Him for this repeatedly.
