What does "fallen" more often mean in Scripture?

Revelation 2:5 (ESV)

5 Remember therefore from where you have fallen; repent, and do the works you did at first. If not, I will come to you and remove your lampstand from its place, unless you repent.

The term fallen appears more often in Scripture to denote falling away from the faith (see Romans 11:11, Romans 11:22; 1 Corinthians 10:12; Hebrews 4:11).
