How do we know that full assurance of faith is true?

Full assurance of faith is not just a subjective feeling but a profound truth grounded in the character and promises of God as revealed in Scripture. Hebrews 10:22 invites believers to approach God with a true heart in assurance, which is anchored in the completed work of Christ. The sacrifice of Jesus serves as the ultimate guarantee of our peace with God. The New Testament emphasizes that this assurance is not dependent on human effort or merit but rather on the unconditional covenant of grace established through Christ. Believers are called to rely on the truth that their sins are forgiven and that they are reconciled to God, and they can have confidence in their salvation as they trust in Christ's righteousness alone.
