To save, to deliver from danger, to heal, to preserve. Sōzō has remarkable range: physical healing ('your faith has saved/healed you'), rescue from danger ('Lord, save us!'), and spiritual salvation ('believe and be saved'). The wholistic scope shows that salvation addresses the whole person.
The angel told Joseph: 'He will save his people from their sins' (Matthew 1:21) — naming Jesus' core mission. Paul declares: 'By grace you have been saved' (Ephesians 2:8). Salvation has three tenses: we have been saved (justification), we are being saved (sanctification), and we will be saved (glorification). Sōzō refuses to separate physical and spiritual — the God who heals bodies also saves souls.
