In order for one to believe the Gospel, certain things must first occur, because by nature, man is blinded by satan and in a state of unbelief when it concerns the Gospel as Per
2 Cor 4:3,
4
3But if our gospel
be hid, it is hid to them that are lost:
4In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
All men[Elect and non elect] by nature are lost, are alienated from the Life of God, and the Gospel is being hid from them, and they are in unbelief.
Before one can believe the Gospel, they must be first rescued from the control of satan. Notice vs 4 above, those who believe not have their minds blinded by the god of this world !, So they are under his control.
Also, Before we can believe the Gospel, we must have been given a Revelation of the Spiritual details of the Gospel , and be capacitated to receive them ! The Gospel must be revealed to Faith, which is a fruit of the Spirit
Rom 1:16-17
16For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
17For therein is the righteousness of God
revealed from faith to faith: as it is written, The just shall live by faith.
Notice the word revealed ! It is the greek word apokalyptō:
to uncover, lay open what has been veiled or covered up
a) disclose, make bare
2)
to make known, make manifest, disclose what before was unknown
Paul spoke by experience, because he testified that he received it [The Gospel] by revelation
Gal 1:11-12
11But I certify you, brethren, that
the gospel which was preached of me is not after man.
12For I neither received it of man, neither was I taught it,
but by the revelation of Jesus Christ.
This is basically the same word revelation as used in
Rom 1:17 revealed !
This is True because the Spiritual details of the Gospel cannot be received by the natural man
1 Cor 2:14
14But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because
they are spiritually discerned.
One cannot receive a spiritual message without spiritually discerning its Truthfulness ! Because we must compare spiritual details with spiritual detail vs 13
Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth;
comparing spiritual things with spiritual.
Paul is speaking of the Gospel here in vs 13 as spiritual things ! Spiritual facts with Spiritual Facts !
So before believing in Christ through the Gospel, one must first be saved from satan's control, his kingdom of darkness
Col 1:13
13Who
hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
And , we must have the Gospel revealed to us, made know to us and we must be spiritually capacitated to receive its spiritual details !
