Most of the time, when we Christians become reckless with things, we become unaware of satanic activities. Consequently, if a pastor tells that something is good, we tend to believe it wholeheartedly. This is the very reason why there is a discerning spirit (1 Cor.12:10) We have to be careful in our faith because Satan do scatter seeds/spirits that would grow in our hearts. Some of these could be spiritual blindness and acceptance of what is evil.
