What a good point to bring up those who have had to 'give up' because there isn't a single church in their community that practices Bibilical worship, will one day realize the hope of true worship when we are all in the presence of a Holy God.
One suggestion for those who have not previously done so is to incorporate a God-centered, theologically sound hymn into personal Bible study and prayer time.
It doesn't replace corporate worship (which is devoid of hymnody, Biblical depth, and God-centered theology), but it helps....
Yep, I read hymns from time-to-time, and joyfully sing along in my car with local "old fashioned" radio that plays hymns!
