[b]Therefore God has mercy on whom he wants to have mercy, and he hardens whom he wants to harden.
19 One of you will say to me: “Then why does God still blame us? For who is able to resist his will?” 20 But who are you, a human being, to talk back to God? “Shall what is formed say to the one who formed it, ‘Why did you make me like this?’”[h] 21 Does not ...[text shortened]... be why would God tempt people to harden their heart, not Paul's words, God hardening the heart.
It isn't a temptation to harden one's heart, it is an invitation to come to God, there are only
two answers to God's call, yes or no. If yes, then He becomes your Lord and Savior, if no
you harden your heart by refusing Him. It is a choice, your will, if you had no will there
would be no judgment since everyone played the part they were given without exception
or choice in the matter. You can only be judged for choices you made, not acts you were
forced to do because there wasn't a choice.
Hebrews 3:8
do not harden your hearts as in the rebellion, on the day of testing in the wilderness,
Hebrews 4:6-8 English Standard Version (ESV)
6 Since therefore it remains for some to enter it, and those who formerly received the good news failed to enter because of disobedience, 7 again he appoints a certain day, “Today,” saying through David so long afterward, in the words already quoted,
“Today, if you hear his voice,
do not harden your hearts.”
8 For if Joshua had given them rest, God would not have spoken of another day later on.
