What does 'from faith to faith' mean in the context of the gospel?

'From faith to faith,' as mentioned in Romans 1:17, indicates that the righteousness of God is revealed progressively in the lives of believers, from the moment they first believe to the ongoing faith they exercise. This phrase highlights that the revelation of God's righteousness is not a one-time event; rather, it is a dynamic relationship that continues as believers grow in their faith. It points to the necessity of both an initial faith in the gospel and a continual faith that sustains the believer throughout their life, grounded in the work of Christ.
