"The term used in Scripture for religion/religious speaks positively of an attitude of mind which results in genuine devotion to God. Acts of mercy, love and holiness, then, are religious. It is not far removed from the term spiritual, which refers to that from the Spirit, in contrast to the flesh, what is carnal.
Biblically speaking, if you are truly spiritual, you naturally would be religious. If your life is focused on those things of God, who is Spirit, then it will influence what you do. Whether in worship or service, religion and spiritual are complimentary terms, as we are "living sacrifices" (religious) who are not conformed to the world but transformed by the will of God (spiritual - Romans 12:1-2)." http://www.gospelgazette.com/gazette/2006/sep/page3.htm
Are there Dangers in Being Spiritual but Not Religious?
"On the opposite end of our natural tendency to moralize life and suffering stands the counter-intuitive affirmation of Christianity. Christianity affirms that Jesus severed the link between suffering and deserving once for all on the cross. God put the ledgers away and settled the accounts. The good news of the Gospel is NOT that good people get good stuff. It's not that life is cyclical and that "what comes around goes around." Rather, it's that the bad get the best, the worst inherit the wealth and the slave becomes a son (Romans 5:8)." Kharma
