Revelation_2v5

Jesus Told The Church At Ephesus to 'Return to Your First Love'
Jesus Said If They Did Not Repent, Their Lampstand Would Be Removed

Revelation 2:4-5

4 But I have this against you: You have abandoned your first love.

5 Therefore, keep in mind how far you have fallen. Repent and perform the deeds you did at first. But if you do not repent, I will come to you and remove your lampstand from its place.

Strong's Exhaustive Concordance

fail, fall down

A reduplicated and contracted form of peto (pet'-o); (which occurs only as an alternate in certain tenses); probably akin to petomai through the idea of alighting; to fall (literally or figuratively) -- fail, fall (down), light on.

see GREEK petomai

Jesus' words clearly reveal that one-time believers are capable of abandoning, and falling away from, their faith, and in fact, were in danger of having their lampstand removed.
