Salvation is of the Lord period. He saves us and keeps us saved.
James 1:18
He chose to give us birth through the word of truth, that we might be a kind of firstfruits of all he created.
John 1:13
children born not of natural descent,
nor of human decision or a husband's will,
but born of God.
1 Peter 1:3
Praise be to the God and Father of our Lord Jesus Christ!
In his great mercy he has given us new birth into a living hope through the resurrection of Jesus Christ from the dead,
Titus 3:5-8
He saved us,
not on the basis of deeds which we have done in righteousness,
but according to His mercy, by the washing of regeneration and renewing by the Holy Spirit, 6 whom He poured out upon us richly through Jesus Christ our Savior,
7 so that being justified by His grace we would be made heirs according to
the hope of eternal life.
Colossians 2:13
When you were dead in your sins and in the uncircumcision of your sinful nature,
God made you alive with Christ.
Philippians 1:6
And I am certain that
God, who began the good work within you,
will continue his work until it is finally finished on the day when Christ Jesus returns
1 Corinthians 1:8
He will sustain you to the end,
so that you will be blameless on the day of our Lord Jesus Christ.
Philippians 1:29
"For to you
it has been granted for Christ’s sake, not only
to believe in Him, but also to suffer for His sake."
2 Timothy 1:9
who has saved us and called us with a holy calling,
not according to our works, but according to His own purpose and grace which was granted us in Christ Jesus from all eternity,
1 Peter 1:3
"Blessed be the God and Father of our Lord Jesus Christ, who according to
His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead."
God saves us, keeps us saved and it is a gift from Him even granting us the faith which saves.
As Paul says: what do you have that you did not receive ?
Its all by His Mercy and Grace.
I would hate to be the person who stands before God and thinks he had something to do with his own salvation. The Glory is all Gods in Salvation.
hope this helps !!!
