Neither of these are contrary to Calvinism, so long as we are on teh same page in terms of definitions. First, all Calvinists believe that man can reject the Spirit. The Bible plainsly says that they can.
I agree that definitions are the problems.
But Calvinism teaches there is an effectual call in passages like 1 Cor 1 that is usually called "Irresistable Grace." It is a bad term, and most reject that terminology I think. If you look at 1 Cor 1, you will see that the "called" are the ones who accept Christ, and they are contrasted with the others who do not accept them.
Some thing occur outside the "normal" procedures that the "Scriptures might be fulfilled",
The calling of Moses, David, Paul, are just a few of those example.
The Bible teaches two calls -- a general call to everyone and a specific or effectual call to the elect. The primitives and hyperCalvinists err by denying the first, and the Arminianistic (such as yourself) err by denying the second. The Bible teaches both and therefore both must be held.
The only way effectual calling can be different than an "Ineffectual calling", is for the "Spirit" to be absent in the ineffectual calling,
Of course the spirit is "God's voice", but if there's no spirit in the calling, then it's not possible for them to
"Reject" God's calling that never came.
Keep in mind that Jesus told Israel to believe his works, if not his words, and that was meant to be an "Effectual calling".
Mt 22:14 For many are called, but few are chosen.
Second, all men have free will. They can do whatever they want. Because of sin, their will is corrupted and is bound by sin so that all they want to do is sin, and they do it freely. Free will is always defined according to nature. So man is free just like God is. But neither are free to do anything. There are things God cannot do because he is limited by his nature.
Once you commit the first sin, the rest really doesn't matter, but the nature on man, that is God's laws written on his heart, saved or lost, otherwise known as our "Conscience", tell us when we've committed a "wrong", even if we don't recognize it as a sin until we learn the law.
Hearing the gospel, it's condemnation of us, and what we must do to be saved, leaves us with the
"CHOICE" of believing/confessing we're sinners/accepting Jesus or rejecting both Gospel/Jesus.
Ac 16:30 And brought them out, and said, Sirs,
what must I do to be saved?
31 And they said,
Believe on the Lord Jesus Christ, and
thou shalt be saved, and thy house.
As you said, man are free like God, we're made in his Image, and that make us "GODS" as well, just not the
"Supreme God".
Ge 3:5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and
ye shall be as gods, knowing good and evil.
Ps 97:7 Confounded be all they that serve graven images, that boast themselves of idols: worship him,
all ye gods.
Joh 10:34 Jesus answered them, Is it not written in your law,
I said, Ye are gods?
Man can't save himself, God can, but won't unless man is willing to enter into a
""blood Covenant" with God, the blood of Jesus and the blood of man's
"body of sin". (old man crucified)
Heb 9:22 and without shedding of blood is no remission.
Mt 26:28 For this is
my blood of the
new testament, (covenant) which is shed for many for the remission of sins.
Heb 9:16 For where a testament is, there must also
of necessity be the
death of the testator.
17 For a testament is of force
after men are dead: otherwise it is of
no strength at all while the testator liveth.
If
we're not willing to crucify the old man, we can't have covenant with Jesus, the old man's death is a "testament" to our covenant with Jesus.
Mr 10:38 But Jesus said unto them, can
ye drink of the cup that I drink of?
Mt 26:39 And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let
this cup pass from me: nevertheless
not as I will, but as thou wilt.
Sacrificing this body of sin is a sacrifice only we can decide to make,
every person is as free to say
not as thou will, but as I wilt,
As Jesus was to say,
not as I will, but as thou wilt.
Le 17:11 For the
life of the flesh is in the blood: and
I have given it to you upon the altar
to make an atonement for your souls: for it is the
blood that maketh an atonement for the soul.
Ro 6:16
Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey;
whether of sin unto death, or of obedience unto righteousness?
