What does it mean that Jesus's name guarantees salvation?

The guarantee of salvation through Jesus’s name is intricately connected to His authority and divine mission. Philippians 2:9-11 states that God has highly exalted Him and given Him a name which is above every name. This authority allows Jesus to fulfill God’s promise of salvation to His people. The proclamation that 'all those whom He foreknew will be glorified' echoes the assurance that those called by His name will indeed be saved. This guarantees that no one who genuinely calls upon His name will be turned away, affirming the efficacy of His sacrificial work.
