Can we forfeit our salvation ?

CAN WE LOOSE OUR SALVATION?
HOW MUCH OF A HEATED DEBATE BETWEEN BRETHREN ALL THESE HUNDREDS OF YEARS? AND HOW MUCH MORE STILL, UP TO THE LORD HIMSELF WILL COME BACK AND WITH LOVE AND GRACE EXPLAIN TO US ALL

IF YOU LOOSE SOMETHING, YOU DONT KNOW WHERE TO FIND IT!
YOU CANT LOOSE YOUR SALVATION, BECAUSE YOU KNOW WHERE TO FIND IT! BUT YOU CAN ALWAYS LEAVE IT!!
PHILIPPIANS 2:12
