Why is trusting in Christ's righteousness important?

The reliance on Christ's righteousness rather than our own is foundational in the Reformed faith. In Romans 8, Paul elaborates on the distinction between living according to the flesh, which is fueled by self-righteousness, and living according to the Spirit, which identifies Christ as our righteousness. The danger of self-righteousness is that it leads to spiritual death, whereas embracing Christ provides life and peace. True comfort comes from knowing that all spiritual blessings are found in Christ alone, highlighting that our standing before God is through His finished work, not our own.
