Armstrongist soteriology emphasizes that salvation means becoming part of the God Family through resurrection. It is not merely forgiveness of sins but entrance into divine glory as a literal member of God's family. Salvation involves both divine grace and human obedience: while God's grace through Christ provides redemption, believers must respond by keeping God's commandments, particularly the Sabbath, feast days, and dietary laws.

Armstrong taught that the majority of humanity is not called to salvation in this age. Rather, God is now selecting a 'firstfruits' group—those in the church—while offering a later opportunity to all others in the Millennium and Great White Throne judgment. This means Armstrongism combines grace with a works emphasis and places salvation within a larger eschatological framework of multiple resurrections and opportunities.
