All of Salvation is of God !
The Gospel of the Grace of God, attributes all of Salvation unto the Eternal Purpose of God 2 tim 1:
9 Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,
It's pretty cut and dry here, paul says:
1.Who saved us ! Who is the us ? see 2 tim 2:10
2. according to His own purpose and grace
3. Which was given us in Christ Jesus before the world began !
And Paul's gospel was centered in these Truths as we see in vs 10
10 But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel:
Thats is the gospel includes the Truths of vs 9..
Salvations moving cause is the Sovereign [rom 9:18] everlasting [ Jer 31:3] and immutable [rom 9:29] Grace of the Triune God [eph 2:4-5] by whom the saints were Chosen in Christ before the foundation of the World eph 1:4, also predestinated to the adoption of Children, in order that all may redound to His Eternal Glory as per rev 7:10
and crying out with a loud voice, "Salvation belongs to our God who sits on the throne, and to the Lamb!"[esv]
The freewillers however would prefer that it be said " Salvations belongs to our god and our freewills"
However
Salvations meritorious cause, that is salvation is not because of anything we did to get saved [faith or believe or repent] not of works of righteousness as stated in titus 3:5, but the meritorious cause is the obedience unto death of the Lord Jesus Christ rom 5:19b
so by the one man’s obedience the many will be made righteous.
phil 2:
8 And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross.
His death was of the Grace, saving Grace of God heb 2:
9But we see him who for a little while was made lower than the angels, namely Jesus, crowned with glory and honor because of the suffering of death, so that by the grace of God he might taste death for everyone.
note: everyone here is limited to the context of everyone of the new covenant sons, which brings them to Glory
10 For it was fitting that he for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering [His Death].
Christ in His death hath obeyed in Behalf of the Sons He brings to Glory, He obeyed the Law for them [ Gal 4:4] enduring in their stead the punishment due unto their sins [ 1 cor 15:3;isa 53:5; gal 3:13] and that His perfect God Honoring Righteousness was imputed to them, as their sins imputed to Him, and this is the meritorious grounds of their complete Justification before God, and not mans freewill...
And Salvations Efficient Cause is the Internal work of the Holy Ghost, phil 2 :13, for He imparts into the soul the principal of life eph 2:1; 1 pet 1:23; 1 jn 3:9, whenever He gives us a New Birth Jn 3:3-8 and delivers us from the power of darkness and translates us into the Kingdom of God's Dear Son, this is His Work in Salvation..
Salvation is therefore by the Three P's of God, The Fathers Purpose of Grace, The Son's Purchase of Grace and the Holy Ghost Power of Grace..
