How does God assure us of our salvation?

Assurance of salvation is provided by the Holy Spirit, who works in the hearts of believers, affirming their relationship with God. In 1 John 3:20-21, John explains that when our hearts condemn us, God is greater than our hearts and knows all things. This means that even in our struggles and doubts, the Spirit assures us of God's eternal purpose in our lives. Moreover, our assurance is reflected in the way we respond to the commands of Christ, demonstrating our love for God and one another. The Spirit also purges our conscience, allowing us to have confidence in our prayers and a clear relationship with God, as noted in Hebrews 10:22. In summary, our assurance rests upon God's promises and the transformative reality of the Holy Spirit in our lives.
