Revelation 14:12,
NIV: "This calls for patient endurance on the part of the people of God who keep his commands and remain faithful to Jesus."
What do you mean during tribulation? Is that 7 years tribulation?
What do you mean faith alone?
Is that mean no matter what you do, killing, not help poor (Matt 25) as long believe Jesus as God save?
And how you know this verse only for people during tribulation
Matt 25
41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
42 For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink:
43 I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not.
Cursed into everlasting fire
Must be hell or not save
