How can I be sure that I have eternal life?

To be assured of eternal life, one must place their faith in Jesus Christ, believing in His atoning work and the truth of Scripture. John writes in 1 John 5:13 that the assurance is given specifically to those who believe in the name of the Son of God. This knowledge is more than intellectual acknowledgment; it involves a heartfelt trust in Jesus' work and promises. By regularly engaging with God's Word and the Gospel, believers can experience a deepening confidence in their eternal security.
