How can Christians be assured of their salvation?

The assurance of salvation for Christians is rooted in the faithfulness of Christ and His redemptive work. According to verses like John 6:37, all that the Father gives to Jesus will come to Him, emphasizing God's sovereign choice and promise of salvation. Furthermore, believers are reminded of the grace of God that is extended to them through Christ, who bore the penalty of sin and reconciled them to the Father. The internal witness of the Holy Spirit and the transformative change in a believer’s life serve as signs of such assurance, confirming that they are indeed part of the elect who have been justified by faith.
