Why is confidence in Christ important for Christians?

Confidence in Christ is vital for Christians because He is the only source of righteousness and the fulfillment of the law. Romans 3:20-24 indicates that no one will be justified in God’s sight through the works of the law; instead, righteousness comes through faith in Jesus Christ for all who believe. By placing our confidence in Christ alone, we acknowledge that He has fulfilled the law on our behalf and that our standing before God relies entirely on His atoning work rather than our efforts. This gives believers the assurance of acceptance with God and the assurance of eternal life.
