Don't be afraid! Regarding the Mark of the Beast, remember the sin is in the will, if forced, it is not a sin, it must be that you know it is an offense of God and you are going to do it anyway. I remember learning in school that even if it wasn't a sin but you believed it was and do it anyway, you are guilty because it is in the will you choose evil over God.
I'm scared too, for my younger loved ones, grandchildren, I am scared for myself that I will persevere no matter what!
Padre Pio's motto was, 'PRAY AND DON'T WORRY." Easier said than done, I know!
