If we are once saved, always saved, then why will Jesus be sorting sheep from goats and telling the sheep “when I was hungry, you gave me food…” and to the goats on his left “when I was hungry and thirsty, you gave me nothing…” Does that help?
Referring to Matthew 25:31-46
[31] “When the Son of man comes in his glory, and all the angels with him, then he will sit on his glorious throne.
[32] Before him will be gathered all the nations, and he will separate them one from another as a shepherd separates the sheep from the goats,
[33] and he will place the sheep at his right hand, but the goats at the left.
[34] Then the King will say to those at his right hand,
Come, O blessed of my Father, inherit the kingdom prepared for you from the foundation of the world; [35] for I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, [36] I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.' [37] Then the righteous will answer him, Lord, when did we see thee hungry and feed thee, or thirsty and give thee drink?
[38] And when did we see thee a stranger and welcome thee, or naked and clothe thee?
[39] And when did we see thee sick or in prison and visit thee?’
[40] And the King will answer them,
Truly, I say to you, as you did it to one of the least of these my brethren, you did it to me.' [41] Then he will say to those at his left hand, Depart from me, you cursed, into the eternal fire prepared for the devil and his angels;
[42] for I was hungry and you gave me no food, I was thirsty and you gave me no drink,
[43] I was a stranger and you did not welcome me, naked and you did not clothe me, sick and in prison and you did not visit me.’
[44] Then they also will answer,
Lord, when did we see thee hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to thee?' [45] Then he will answer them, Truly, I say to you, as you did it not to one of the least of these, you did it not to me.’
[46] And they will go away into eternal punishment, but the righteous into eternal life.”
