What does the Bible say about knowing if we are born again?

The Bible assures believers that they can know they are born again through several means. Firstly, in 1 John 5:1, Scripture states that those who believe that Jesus is the Christ are born of God. This faith in Christ is foundational to our assurance of salvation. Additionally, the witness of the Spirit, as described in 1 John 5:10, conveys that the Holy Spirit within us testifies to our being children of God. Furthermore, love for the brethren serves as evidence of our new birth, as outlined in 1 John 3:14, signifying a transformation of our affections and priorities in Christ's love.
