“Plead my cause, O Lord, with those who strive with me; Fight against those who fight against me.” (Psalm 35:1 NKJV).

David cried out to the Lord to be both his advocate and avenger. He prayed that the Lord would “plead” his case as a defense attorney would one falsely accused, and “fight” for him as a warrior defending his own.
Yet, what David brought before the Lord as a prayer, those in Christ can depend on as a promise. The Lord Jesus is our Advocate. As the apostle John wrote, “… if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous” (1 John 2:1). And the Lord Jesus is our Avenger. As the apostle Paul wrote, “Beloved, do not avenge yourselves, but rather give place to wrath; for it is written, ‘Vengeance is Mine, I will repay,’ says the Lord” (Romans 12:19).
David’s prayer has become our promise. Jesus is our Advocate and Avenger.
