I have often wondered this myself .... a person who believes in Christ & follows his teachings vs liberal/Obama seems incompatible to me. One lesson I learned a couple of years back while watching someone die (struggling with the existence of God - afraid to die because of fear of the unknown) ..... a lot of "Christians" warm a church pew for years and never develop a personal relationship with God. I think this lack of a true, personal relationship makes it easier to make excuses/be tolerant of sinful behavior like abortion/murder, homosexuality, and the general Godless behavior that is going on in this country.
Or simply as long as you “believe”, perception is okay.
