What does it mean to believe on the name of Jesus?

To believe on the name of Jesus signifies a deep trust in all that He is and represents. His name encapsulates His attributes—mercy, grace, justice, and power. John 1:12 connects belief in His name with the privilege of becoming a child of God. It's not simply about verbal acknowledgment of Jesus' name; it represents faith in His redemptive work and His ability to save. Calling upon His name for salvation means relying wholly on His character to save us, as expressed in Acts 16:31, 'Believe on the Lord Jesus Christ, and thou shalt be saved.'
