THE GREAT GAUNTLET OF TRUE CHRISTIAN FAITH:
do you wish Hitler had repented?!

I do!

2 Peter 3:7-13
By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of the ungodly. But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day.  The Lord is not slow in keeping his promise, as some understand slowness. Instead he is patient with you, not wanting anyone to perish, but everyone to come to repentance. But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare. Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives  as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat. But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells.

Hebrews 3:14
We have come to share in Christ, if indeed we hold our original conviction firmly to the very end.

Hebrews 6:4-6
It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit, who have tasted the goodness of the word of God and the powers of the coming age and who have fallen away, to be brought back to repentance. To their loss they are crucifying the Son of God all over again and subjecting him to public disgrace.

Luke 12:8-10
“I tell you, whoever publicly acknowledges me before others, the Son of Man will also acknowledge before the angels of God.  But whoever disowns me before others will be disowned before the angels of God.  And everyone who speaks a word against the Son of Man will be forgiven, but anyone who blasphemes against the Holy Spirit will not be forgiven.
