Summary: At the beginning of King Davi’s reign, this Psalm was his commitment to purity in his home. Today, it eshorts us to guard the purity of our lives and our homes.
"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.”
Literally, this word meant "a thing of Belial." Belial was a false god. David promises not to allow false religion into his home. He promised that he would not allow himself to look upon the false gods of his day. We can learn much from David’s commitment. We should have no contact with anything associated with evil. Think about the shows on televison. They are all to often filled with false ideas contrary to our God. Our Lord is offended as we laugh at the sinful practices of this world. There is little difference between our tolerance of evil entertainment and someone in David’s world tolerating false idols in their homes.
Scripture informs us to separate from ungodly influence, (Psalm 1:1) " Blessed is the man who does not walk in the counsel of the wicked or stand in the way of sinners or sit in the seat of mockers."
Further, we are instructed to separate from carnal Christians. " It is actually reported that there is sexual immorality among you, and of a kind that does not occur even among pagans: A man has his father’s wife. . .But now I am writing you that you must not associate with anyone who calls himself a brother but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat." (1 Corinthians 5:1,11)
We are also told to separate from all sinful activity. "Have nothing to do with the fruitless deeds of darkness, but rather expose them. For it is shameful even to mention what the disobedient do in secret." (Ephesians 5:11-12)
