How do we know that Christ is all in our salvation?

Throughout the Scriptures, salvation is portrayed distinctly as being accomplished through Christ alone. He is our Redeemer, bearing the sins of His people and fulfilling all righteousness on their behalf. Without Him, there is no redemption, as seen in Romans 3:22-26, which emphasizes that righteousness comes through faith in Jesus Christ to all who believe. Therefore, to grasp the full implications of our salvation, one must recognize that Christ does not merely play a part; He is everything, as He saves, justifies, and reconciles sinners to God, ensuring that the believer's relationship with God is solely through Him.
