Anger, hate, strife, jealousy, bitterness, hard heartedness, unbelief, stubbornness, pride, lust, envy, unforgiveness, slander, conspiring, crime, backstabbing, dishonesty, lying, cheating, disloyalty...All hidden mindsets, with hidden agendas never exposed to death.
We don't want other believers to think we are not spiritual (enough) so we try to overrule their arguments with answers like " Yes but the Lord told me" or " Do you think I cannot hear from God? " or " I just do as God told me to" such terrible remarks without blinking our eyes, and the worse thing about it is, we truly believe it ourselves.
