How are believers marked as elect of God?

In Revelation 14:1, the 144,000 are described as having the Father's name written on their foreheads, symbolizing their election and belonging to God. This marks them as set apart and preserved, reflecting God's sovereign grace and His everlasting covenant with His chosen people. Throughout Scripture, election signifies God's choice before the foundation of the world (Ephesians 1:4-5). This name signifies not only belonging but also the assurance of salvation; those marked by God will never perish (John 10:28-29). Thus, the concept of being chosen and sealed by God gives believers the assurance of His eternal commitment and love toward them, reinforcing their identity as members of God’s family.
