Soteriologie
The doctrine of salvation, encompassing the entire scope of God's redemptive work from election to glorification. Soteriology addresses how sinful humanity is reconciled to a holy God. Key concepts include election (Ephesians 1:4), calling (Romans 8:30), regeneration (Titus 3:5), conversion (Acts 3:19), justification (Romans 5:1), adoption (Galatians 4:4-5), sanctification (1 Thessalonians 4:3), perseverance (Philippians 1:6), and glorification (Romans 8:30). Ephesians 2:8-9 summarizes: 'By grace you have been saved through faith — and this is not from yourselves, it is the gift of God — not by works.'
