I have always been fascinated by the School Districts 'zero hands on' policy. They have no tolerance whatsoever for any pupils who put their hands on another, even if one of the pupils is defending himself. It's true, it happened to my son at one time.
In Psalm 101 we have a 'zero tolerance policy' against evil. You can simply not allow it to take root in your life and bloom, the results will be devastating.
Psalm 101 puts it so eloquently.

3 things we will look at::
1) The OBJECT of our Commitment, 2) a commitment to a PURE LIFE, and 3) a commitment to a PURE HOME.

“I will sing of your love and justice; to you, O Lord, I will sing praise" (Psalm 101:1).
David’s song is to the Lord (to you). His desire is to speak of the Lord’s love and justice. His focus in establishing a home of purity was to please the Lord who treated David according to His love, and demanded justice from all those who follow Him. These two thoughts are not contradictory to one another. God’s love never excuses sin. In His love He demands that we obey. David understood the relationship of these two attributes.

In our day of permissiveness and tolerance, we must remember that God will judge sin. We ought not misinterpret His patience with thinking He overlooks our sinful behavior. When David himself sinned against God, he confesses that "to you and to you alone have I sinned” (Psalm 51:4). Had David heeded the words of his own song in Psalm 101, he would not have needed the words of confession he prayed in Psalm 51!

"I will be careful to lead a blameless life— when will you come to me? I will walk in my house with blameless heart. I will set before my eyes no vile thing. The deeds of faithless men I hate; they will not cling to me. Men of perverse heart shall be far from me; I will have nothing to do with evil." (Psalm 101:2-4)

Here, David speaks of guarding his personal life. He mentions having a “blameless life” three times in these three verses. Blameless had the idea of being "without blemish," a reference to the standard of perfection required for the animal sacrifices offered to the Lord. The root of this word dealt with something complete. Nothing could be lacking. The same word is used in Proverbs 28:18 "He whose walk is blameless is kept safe, but he whose ways are perverse will suddenly fall." David commits himself to walk before the Lord with a blameless heart.

The place to begin a blameless heart is in our home. You might put on a good front on Sunday mornings, but your family knows the real you. They see how you respond to difficulty. They know what books you are reading, and what shows you are watching. They hear your unguarded language. David commits himself to lead a life of integrity beginning in his own home.

He commits "I will set before my eyes no vile thing." The world vile means "worthless or wicked.” It is used in Proverbs 6:12 (KJV) "A naughty person, a wicked man, walketh with a froward mouth." Another occurrence of this is found in Proverbs 6:12 (NIV) "A scoundrel and villain, who goes about with a corrupt mouth.” Also, Proverbs 16:27 declares “A scoundrel plots evil, and his speech is like a scorching fire.”


Some questions to ponder:

1) How can you live a blameless life and be innocent of wrongdoing? Is it possible to have a perfect heart?

2) We are told to live apart from the wicked. In living such a separated life, does that keep you from being effective in sharing the Gospel with those who need it most?

3) Jesus lived his life among sinners. Was that because He had no choice, being the only one to ever live a perfect life? How do Jesus’ interactions with sinners compare with the counsel given in this psalm?

4) As Jesus’ followers, how can we love the wicked without being influenced by them?
