How do we know our righteousness comes from Christ?

The doctrine of imputed righteousness is central to Reformed theology and is highlighted in passages like Philippians 3:9, which emphasizes that believers are to be found in Him, having a righteousness not of their own, but from God through faith in Christ. This means that our standing before God is based solely on Christ's perfect obedience and sacrifice. As believers, we must recognize that if we depend on our righteousness or good works, we are not abiding in Christ. Rather, our identity, acceptance, and justification come exclusively through Him.
