How can we be sure of our salvation according to the Bible?

The assurance of salvation is rooted in the promises of Christ and the security of His work for believers. 1 John 5:13 states that those who believe in the name of the Son of God may know they have eternal life. True faith, as a gift from God, transforms the believer's heart and produces love for God and His people, indicating that genuine salvation has occurred. Furthermore, Ephesians 2:8-9 emphasizes that salvation is not by works but is a gift through faith. This unmerited grace assures us that if we cling to Christ and His righteousness, we are secure in His love.
