Shalom,Actually "Freewill" is a Biblical principal:Lev 22:18 Speak unto Aaron, and to his sons, and unto all the children of Israel, and say unto them, Whatsoever [he be] of the house of Israel, or of the strangers in Israel, that will offer his oblation for all his vows, and for all his
freewill offerings, which they will offer unto the LORD for a burnt offering;Lev 22:21 And whosoever offereth a sacrifice of peace offerings unto the LORD to accomplish [his] vow, or a
freewill offering in beeves or sheep, it shall be perfect to be accepted; there shall be no blemish therein.Lev 22:23 Either a bullock or a lamb that hath any thing superfluous or lacking in his parts, that mayest thou offer [for] a
freewill offering; but for a vow it shall not be accepted.Lev 23:38 Beside the sabbaths of the LORD, and beside your gifts, and beside all your vows, and beside all
your freewill offerings, which ye give unto the LORD.Num 15:3 And will make an offering by fire unto the LORD, a burnt offering, or a sacrifice in performing a vow, or in a
freewill offering, or in your solemn feasts, to make a sweet savour unto the LORD, of the herd, or of the flock:Num 29:39 These [things] ye shall do unto the LORD in your set feasts, beside your vows, and
your freewill offerings, for your burnt offerings, and for your meat offerings, and for your drink offerings, and for your peace offerings.Deu 12:6 And thither ye shall bring your burnt offerings, and your sacrifices, and your tithes, and heave offerings of your hand, and your vows, and
your freewill offerings, and the firstlings of your herds and of your flocks

eu 12:17 Thou mayest not eat within thy gates the tithe of thy corn, or of thy wine, or of thy oil, or the firstlings of thy herds or of thy flock, nor any of thy vows which thou vowest, nor
thy freewill offerings, or heave offering of thine hand

eu 16:10 And thou shalt keep the feast of weeks unto the LORD thy God with a tribute of a
freewill offering of thine hand, which thou shalt give [unto the LORD thy God], according as the LORD thy God hath blessed thee

eu 23:23 That which is gone out of thy lips thou shalt keep and perform; [even] a
freewill offering, according as thou hast vowed unto the LORD thy God, which thou hast promised with thy mouth.2Ch 31:14 And Kore the son of Imnah the Levite, the porter toward the east, [was] over the
freewill offerings of God, to distribute the oblations of the LORD, and the most holy things.Ezr 1:4 And whosoever remaineth in any place where he sojourneth, let the men of his place help him with silver, and with gold, and with goods, and with beasts, beside the
freewill offering for the house of God that [is] in Jerusalem.Ezr 3:5 And afterward [offered] the continual burnt offering, both of the new moons, and of all the set feasts of the LORD that were consecrated, and of every one that willingly offered a
freewill offering unto the LORD.Ezr 7:13 I make a decree, that all they of the people of Israel, and [of] his priests and Levites, in my realm, which are minded of
their own freewill to go up to Jerusalem, go with thee.Ezr 7:16 And all the silver and gold that thou canst find in all the province of Babylon, with the
freewill offering of the people, and of the priests, offering willingly for the house of their God which [is] in Jerusalem:Ezr 8:28 And I said unto them, Ye [are] holy unto the LORD; the vessels [are] holy also; and the silver and the gold [are] a
freewill offering unto the LORD God of your fathers.Psa 119:108 Accept, I beseech thee, the
freewill offerings of my mouth, O LORD, and teach me thy judgments. What is the ultimate "Freewill offering?" To lay ones life down for another!Y'SHUA showed us this when He laid His life down to do only that of His and our FATHER...Jhn 5:19 Then answered Jesus and said unto them, Verily, verily, I say unto you,
The Son can do nothing of himself, but what he seeth the Father do: for what things soever he doeth, these also doeth the Son likewise.andJhn 5:30
I can of mine own self do nothing: as I hear, I judge: and my judgment is just;
because I seek not mine own will, but the will of the Father which hath sent me.Lastly...Luk 22:42 Saying, Father, if thou be willing, remove this cup from me: nevertheless
not my will, but thine, be done.Did Judas have 'freewill?' Absolutely! He could have made the same choice we are given. The same choice Y'SHUA made often to include when He was on the cross and after He had risen...Jam 4:7 Submit yourselves therefore to God. Resist the devil, and he will flee from you.But why would Judas have made this choice? Actually because he was such a Zealot for YHVH that YHVH actually knew HE could trust him to do this and yet do the right thing thereafter...Mat 27:3 Then Judas, which had betrayed him, when he saw that he was condemned,
repented himself, and brought again the thirty pieces of silver to the chief priests and elders,Judas repented! He didn't understand but he did know where or how to turn to receive help, forgiveness!What of the hardening of Pharaoh's heart then? He chose of his own freewill to treat the Jews unfairly before YHVH. He told Moses that he would release them if YHVH would remove the plagues and then did not - Ex 8:1-15Did YHVH create everything or not? If HE did then HE foreknew ALL of us, did HE not? According to The Scriptures...Rom 8:29 For whom he did foreknow, he also did predestinate [to be] conformed to the image of his Son, that he might be the firstborn among many brethren.What is it saying here? It is saying that since HE has foreknowledge of ALL of us that HE has made ALL of us to be conformed to the image of Y'SHUA. HE has made us ALL for this but not ALL will come to the knowledge of The CHRIST will they? Why not? because we still have a freewill choice just as the angels had when a third chose to follow satan, just as Judas and Pharaoh had, just as Y'SHUA had!
