Convictions which you feel emotional and passionate about define you to others. If your feelings should change, do you think your character and soul will suffer? No. Strength of mind and individuality are not defined by herd mentality. Emotions should work WITH your mind, not over it.
In The World To Come you will be judged by your compassion, acceptance, and love toward ALL life. This is acting in the manner of what American Indians called The Great Spirit In The Sky. It is sanctimonious to believe that those who act and think differently than you are less meaningful to that Spirit. Consider that.
