Assurance of faith comes from believing in Christ's finished work and experiencing the Holy Spirit’s conviction.
The assurance of faith is not something we manufacture but is a product of God's revelation of Christ to us through the Holy Spirit. Romans 10:17 says, 'So then faith comes by hearing, and hearing by the word of God.' When the Spirit brings the gospel to our hearts, convicting us of sin and revealing Christ’s righteousness, we are enabled to believe and rest in Him. This process reflects a transformative work of God, which produces in us a confidence not in our abilities or decisions but in Christ crucified and risen. It is by looking to Christ as the author and finisher of our faith that we can have the assurance of our eternal standing before God.
