Psalm 101:7-8

⁷ He who works deceit shall not dwell within my house;
He who tells lies shall not continue in my presence.

The liar and the one who works to create confusion shall not dwell in the house of the lord.  He will not tolerate such in His presence.  This verse could also have been written from David about his own house and he is saying that he will not allow those who lie to dwell in his house and he will not let them continue in his presence. 

Either way, the only way to keep someone from dwelling in your home or continuing to tell lies in your presence is to confront them.  There has to be a confrontation where the lies are asked to be defined and the person must stand accountable for them.  I believe it is extremely important for Christian homes to be firm on this.  Make every word accountable, let your ‘yes’ be ‘yes’ and your ‘no’ be ‘no’.  We must train ourselves and our children to be accustomed to confrontation on their actions and willing to confront others.  Any type of passive resistance is vague and non-specific and creates unresolved emotions between family members and should be avoided.  If someone is lying they should be confronted about it and their future intentions clarified so everyone knows what direction they are going or what spiritual target they’re aiming towards.

⁸ Early I will destroy all the wicked of the land,
That I may cut off all the evildoers from the city of the Lord.

Evil will not be allowed to prosper.  When it is recognized it will be destroyed quickly so that they do not access the holy city.  We would do well to learn this in our own lives.  When sin in our life is recognized we should be adamant to destroy it quickly.  We should find a way to not let it roost and close the gap so no foothold can be established.  By being vigilant to watch and destroy it we will keep it from corrupting our spirit, our peace, our love, our perception of others, our joy, and our hope.  It will not seep in and come between us and our Lord.
