The Holy Spirit reveals Salvation to Gods Elect !
Jesus indicates as much here Jn 16:13-15
13 Howbeit when
he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
14 He shall glorify me:
for he shall receive of mine, and shall shew it unto you.
15 All things that the Father hath are mine: therefore said I, that he shall take of mine, and
shall shew it unto you.
This isnt just a promise to Christ's disciples, but to His Church, His Body He was about to give Himself for Eph 5:25-26,
The Spirit is given to all the redeemed in order that they may come to know the things freely given to them as Gifts of Redemption so Paul writes 1 Cor 2:7-12
7 But we speak
the wisdom of God [The Gospel of Christ 1 Cor 1:24] in a mystery, even the hidden wisdom, which God ordained before the world unto our glory:
8 Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
10 But
God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
The Spirit is given to the redeemed one in order to give them a experimental knowledge of Salvation, things freely given them of God, which things accompany the giving of Christ for them as Per Rom 8:32
32 He that spared not his own Son, but delivered him up for us all,
how shall he not with him also freely give us all things?
And so the Spirit is given along with Christ in order to show, reveal to the hearts and minds, conscience of the redeemed those things freely given to them with Christ !
One such thing freely given is forgiveness , pardon. The greek word for freely given in 1 Cor 2:12 is charizomai and primarily means :
properly, to
extend favor ("grace"), freely give favor to grant forgiveness (pardon).
xarízomai (
"favor that cancels") is used of God giving His grace to pardon. This is freely done and therefore not based on any merit of the one receiving forgiveness.
[5483 (xarízomai) literally means, "to exercise grace, freely show favor," i.e. willingly ("graciously") bestow.]
All for whom Christ was given, God graciously bestows upon them in His court of Law and Justice forgiveness of sins according to the richs of His Grace Eph 1:7
In whom we have redemption through his blood,
the forgiveness of sins, according to the riches of his grace;
Now this be one of things the Spirit is given for, to make their forgiveness known unto them !
