How can we have assurance of salvation?

Assurance of salvation is firmly rooted in faith in Jesus Christ, who is the Son of God. According to 1 John 4:15, all who confess that Jesus is the Son of God have God dwelling in them and they in God, which establishes a personal relationship based on faith rather than mere intellectual agreement. This mutual indwelling signifies that the believer is secure in their relationship with God, guaranteed by the finished work of Christ on the cross. Furthermore, as believers experience the fruits of the Spirit and the transformative power of grace in their lives, they grow in assurance as they see the evidence of salvation reflected in their spiritual journey.
