What does it mean that God justifies and glorifies us?

In Romans 8:30, it states, 'Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.' This sequential process highlights the certainty of salvation for those whom God has chosen. Justification is God declaring the sinner righteous on the basis of Christ's work, while glorification refers to the ultimate transformation of believers into Christ's image at the resurrection. Understanding both concepts reinforces the assurance that all of God's elect will be fully redeemed, eternally secure in His presence.
