How do we know faith is a continuous work?

The nature of true saving faith is a continual present work, as articulated by Peter in his epistles. Hebrews 10:39 states that believers are not of those who draw back but of those who believe to the saving of the soul. This indicates that genuine faith consistently operates throughout a believer's life and is essential for persevering until the end. It is wrong to equate faith with a singular past event; rather, it must be viewed as an active principle that sustains a believer's journey in sanctification.
