Lord, set up a guard for my mouth; keep watch at the door of my lips. Do not let my heart turn to any evil thing or wickedly perform reckless acts with men who commit sin. Do not let me feast on their delicacies. Let the righteous one strike me—it is [an act of] faithful love; let him rebuke me—it is oil for my head; let me not refuse it. Even now my prayer is against the evil acts of the wicked. When their rulers will be thrown off the sides of a cliff, the people will listen to my words, for they are pleasing (Psalm 141 vv. 3-6).
David had the right idea. His aspirations were lofty; he was just too human to attain them! Still, he longed to be pure, blameless, and sanctified (set apart).
In this passage he submits three parts of his body to the Lord for cleansing—his lips and mouth, lest he speak evil (v. 3); his heart, lest he become involved in sensual pleasures (v. 4); his head, lest his mind toy with the evil schemes of the wicked (v. 4). In fact, he asks for corrective support from godly friends.
God never intended for us to face life alone. If we isolate ourselves from real, down-to-earth relationships, the enemy will subtly distract us, seduce us, and then devour us. My close friends regularly pray for me, communicate with me, and generally hold me accountable. Karen and I also attend small group Bible studies where we experience rich Christian fellowship in a private setting. Without this support, we would be depriving ourselves of one of the greatest blessings the Lord gives us—intercessory prayer.
In unity there is strength to endure temptation, to make a frontal attack on societal sins, and to stand firm against the enemy. God has set me apart for his ministry, but he has also blessed me with godly friends who pray for me and point out possible dangers I am too blind to see.
O Lord, I thank you again for prayer warriors who faithfully hold me up in prayer. I know you have brought these people into my life to help me fight the battle… and win!
