We are to give no
place to the devil.
If you don't give 'place' to a person it means you do not entertain their presence, their words or their ideas.
By being Tolerant you are giving 'place' to the person being tolerated. If the ideas and words of this person are of satan you should make this clear to them. It is an act of Love to share the Truth . To do otherwise is an act of hate.
Stop being Tolerant . Start being Obedient to Christ . Do it in Love and watch the unbeliever be changed.
