Does Mankind Have An ABSOLUTE Free-Will Regarding His Salvation  
 

If ALL mankind is devoid of individual Free-Will, and therefore one man is PREDESTINED (Made) of God to Eternal Life, while another is PREDESTINED (Made) of God to Sin and Eternal Damnation, then God would indeed be the author and creator of both RIGHTEOUSNESS and UNRIGHTEOUSNESS - Eternal Life and Eternal Death.

I do not know how much more clear God would have to make it to men, than the CONDITIONAL REQUIREMENT of FAITH regarding INITIAL Salvation (New Birth), other than in Acts 16:30. 

In the below cited Passages, when Apostle Paul and Silas had been thrown into jail for their FAITH, and while they were singing praises unto God, a great earthquake fell, shaking the very foundations of the prison where they were being kept.  The KEEPER of the prison, seeing that the doors of the prison and all prisoner bands had been loosed, drew out his own sword and MADE the CHOICE to COMMIT SUICIDE, except for the CRY of Apostle Paul. 

As such, calling for a light and thrusting himself into where Paul and Silas were imprisoned, the Keeper fell down TREMBLING before them, from the fear of the majestic events that he had just experienced,  He thus brought Paul and Silas out and asked the ALL important question, "WHAT MUST I DO TO BE SAVED?"

Please note the use of the greek words in this Passage, dei (G1163) translated as MUST, the personal pronoun I (G3165 - me), and poieo DO, (G4160).   

To this end, the KEEPER wanted to know what ACTION he himself, NOT GOD or PREDESTINATION, MUST DO in order to be SAVED, with Paul and Silas declaring Believe on the Lord Jesus Christ, and thou shalt be SAVED...   

If God PREDESTINES (Makes) UNRIGHTEOUS Vessels of Wrath...then why are those who are made to be "objects of His wrath" in this life, still judged in His 'JUDGMENT'?

We as individuals are 'Formed' and 'Fashioned' by God in direct response to how we exercise our individual God GIVEN Free-Wills in Faith Believing, of and towards His Word.

Many suggest the implied Calvinist view of 'free-will' vs. 'free-choice'... Calvinists typically hold that we are incapable of doing anything good by our own natural powers (subsequent to and because of the original Sin). As such, we have the freedom to choose between alternatives such as (eating apple pie or drinking milk), etc., etc.

Meanwhile, Calvinists teach that it is not God's will to Save ALL Mankind, but only the ELECT and that Christ died only for the ELECT and not for EVERYONE, and therefore, election is unconditional and not based on any foreseen merits.

However, with respect to our ABSOLUTE God given FREE-WILL, to either accept or reject, God's PREORDAINED/PREDESTINED Plan of Salvation in the Blood of Yeshua Jesus, I humbly submit the following support. 

2 Peter 3:9 (KJV)
9 The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any
 should perish,  but that all should come to repentance.
   
John 3:16 (KJV)
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have 
everlasting life.   

1 Timothy 2:4 (KJV))
4 Who4 Who will have all men to be saved, and to come unto the knowledge of the truth.        

Revelation 22:17 (KJV)
17 And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.

In addition, Jesus came FIRST unto the Jews [the ELECT - His own] who WILLFULLY rejected Him.     

John 1:11 (KJV)
11 He came unto his own, and his own received him not.

Please note in 2 Peter 3:9 above, that it is NOT the WILL of the Lord that ANY should perish, but that ALL should repent.  Therefore, this begs the question, IF man does indeed 'perish' (is LOST) because of his UNBELIEF, then just whose WILL actually is it - the Lord or man himself?

Meanwhile, with respect to Matt. 22:14 and 26:16, "For MANY are CALLED but FEW are CHOSEN," how can MANY be CALLED if the PREDESTINED are the ONLY ones ELECTED/Made to be SAVED?  Likewise, Jesus declared in Lk. 10:2, "...The harvest is GREAT but the laborers are few, PRAY therefore that the Lord of the harvest will send laborers into the harvest."  If Jesus was not concerned that the potential harvest would spoil in the field, then why PRAY for more laborers?
