Mosiah 2:36-37

36 And now, I say unto you, my brethren, that after ye have known and have been taught all these things, if ye should transgress and go contrary to that which has been spoken, that ye do withdraw yourselves from the Spirit of the Lord, that it may have no place in you to guide you in wisdom's paths that ye may be blessed, prospered, and preserved-
37 I say unto you, that the man that doeth this, the same cometh out in open rebellion against God; therefore he listeth to obey the evil spirit, and becometh an enemy to all righteousness; therefore, the Lord has no place in him, for he dwelleth not in unholy temples.

Once we have knowledge of right and wrong, once we have been taught a higher law, if we decide to act contrary to that knowledge, we are openly rebelling against Heavenly Father and the Spirit will withdraw. Some of the benefits of the Holy Ghost's companionship are noted here- guidance in wisdom's paths, blessings, prosperity, and preservation. When I look at it in this light, it seems ludicrous that I would ever choose to act against the Spirit and lose the blessings of its guidance. So, not only are we acting against the Spirit, we are openly rebelling against Heavenly Father AND we are choosing to follow Satan. Why??? Why would we ever choose misery over happiness? I don't think most people look at it like this- so black and white. Satan must use sly tactics, lies, and deception to ensnare us. When I think of "becoming an enemy to all righteousness" so that "the Lord has no place in [me]", I can barely stand the thought. I yearn for the day that I will see the Savior again; that I will be able to sit at Heavenly Father's feet and feel the familiar, loving embrace of Heavenly Mother. To not be with Them, to not be with my own eternal family, to not have Lance for eternity would be eternal hell indeed.
