We know Christ is our Savior through the preaching of the gospel and the revelation of Scripture that declares His works for our redemption.
The confidence in Christ as our Savior comes from the preaching of the Word of God, which reveals His person and works. In Acts 8, when Philip preached to the eunuch, he began with the Scriptures and proclaimed Jesus as the fulfillment of those prophecies. The eunuch's question, 'of whom speaketh the prophet this?' led to a clear explanation of Christ’s substitutionary atonement. This same message is the foundation of our faith; we believe not based on our feelings or experiences, but on the truth of God’s Word which reveals Christ as the only means of salvation.
