Why is trusting in God's righteousness important?

In Psalm 143:2, David highlights the crucial truth that no person can be justified by their own works before God. The importance of trusting in God's righteousness stems from the belief that true justification is found only in Christ's completed work. This trust does not hinge on the believer's merits or failures, but rather on the righteousness that God provides through faith in Jesus Christ. This position offers believers comfort and confidence in their relationship with God, knowing that their acceptance is secured by Christ's righteousness.
