I am a bit like that as well "nature lover" I consider myself by nature a realist and a bit of a skeptic as well. I was brought up as a Protestant Christian, but I understand I was never baptised or Christened, my sister was, she became a Roman Catholic when she married. I am not against religion, in fact I enjoy listening to a lot of religious classical music i.e I have 2 CD's of Handels Messiah, so I am not completely against religion. When I was a child it would have been just as bad not to attend 'Sunday School' on a Sunday as it was to miss day school, Monday to Friday. However, like you,it just never 'clicked' to become really religious. I live in Scotland UK, and attendance at both Catholic Chapel and Protestant Church in this country is as low as 10% of the population. The only time that I am in a church, usually a Catholic one, is when my R. Catholic sister takes me to a choir concert in that church, I love the music. I have not been to a Protestant Church Service for nearly 30 years.As I say I have nothing against it, but it just never clicked with me, maybe I am just a little religious as sometimes I read the text while listening to the music.That was a very well thought out testimony. I understand how you feel. I too was baptised, first as an infant in the Catholic church, then being dunked under water in my young adulthood in a Baptist church and finally in an Evangelical church. I too never felt any different or special. I never felt comfortable in any church or gathering among Christians and decided that if I would communicate with my Creator, it would be in my back yard or in the woods or beach where I could enjoy the wonders of nature. I've always tried to believe in the promise of Jesus because the words attributed to Him are very wise. I just never felt any power of the Holy Spirit in the way that most Christians proclaimed they did. Maybe because I'm a skeptic at heart. My older sister is a bible thumping born-again Christian and we butt heads all the time. Her faith is blind and accepting of all. I question everything, maybe too much.
Like you I love nature, love walking in the country and I do a lot of cycling, particularly during the summer months.
