How is assurance of salvation provided in the Bible?

The assurance of salvation is a significant theme in Scripture, particularly emphasized in the intercessory prayer of Jesus found in John 17. There, Christ assures His followers of their position in Him, claiming their eternal safety upon the completion of His redemptive work. Assurance is fortified through understanding that our relationship with God is grounded in His righteousness and justice, validated by the blood of Christ. This solid foundation allows believers to confidently rest in their salvation, upheld by God's grace and the transformative power of the Gospel.
