All of Israel is Saved

See also Eternal Salvation

Matthew 7:21 Not all who say to Me ‘Prince, Prince!’ shall enter into the kingdom of the heavens, but he doing the will of My Father who is in the heavens. 22 Many shall say to Me in that day ‘Prince, Prince, have we not prophesied in Your name, and cast out demons in Your name, and have done many works of power in Your name?’ 23 And then shall I profess to them that ‘Never have I known you! Depart from Me, those who are working at lawlessness!’

No matter what men do or say, the covenants were made only with the children of Israel. Yahweh's words at Amos, where it was spoken to Israel that “you only have I known of all the families of the earth”, have never changed. Even if they seem to do well, the aliens cannot do well, since they can never honestly admit to Yahweh's exclusive relationship with Israel, and with His exclusive promises to preserve Israel. False teachers want to offer preservation to the aliens after the Second Advent, but the Bible makes it clear that only the children of Israel shall inherit the earth.

Because we are all sinners and have all been saved - we must show mercy to our brethren

Matthew 6:14 For if you would remit for men their transgressions, your heavenly Father shall also remit for you. 15 But if you should not remit for men their transgressions, neither shall your Father remit your transgressions.

This goes hand-in-hand with the fact that all Israel shall be saved, that all Israel shall be justified, that every Adamic soul shall ultimately share in the salvation of the tree of life. (The citations for these statements are Romans 11:26, Isaiah 45:25 and Genesis 3:22.) If we judge our brother harshly, Yahweh shall judge us harshly. We have done, or thought to do, many of those same things for which we judge our brother. But to remit, or forgive, a man's transgressions, the man must be repentant in the first place, repentance includes a cessation of the sinful activity we are repenting from. One need not forgive a sinner who is unrepentant. For this reason Paul said in 1 Corinthians chapter 6:

“9 … Do not be led astray: neither fornicators, nor idolaters, nor adulterers, nor effeminates, nor homosexuals, 10 nor thieves, nor covetous, nor drunkards, nor railers, nor rapacious shall inherit the kingdom of Yahweh. 11 And these things some of you may have been, but you have cleansed yourselves; moreover you have been sanctified, moreover you have been deemed fit, in the name of Prince Yahshua Christ, and in the Spirit of our God.”

Paul also explained in 1 Corinthians chapter 5 that unrepentant sinners are to be put out of our community. However once a brother repents, he can find forgiveness with God, and we must also forgive him.
