How can we be sure of our salvation in Christ?

Assurance of salvation is rooted in the believer's faith in Jesus Christ, who baptizes us with the Holy Spirit, as revealed in Mark 1:8. This spiritual baptism signifies our new birth into the family of God, sealing us with the Holy Spirit. Furthermore, according to 1 Corinthians 12:3, one cannot proclaim Jesus as Lord without the Holy Spirit's testimony in their heart. This inner witness confirms that a true transformation has occurred, allowing believers to confidently affirm their salvation based on Christ's completed work and the Spirit's ongoing presence in their lives.
