By God's grace alone are we saved. Without the grace of God, we are nothing, can do nothing, can be nothing - but lost. I'll let God speak for Himself.
I'll start with the greeting of Paul, to his spiritual siblings
Grace and peace to you from God our Father and the Lord Jesus Christ. (1 Cor. 1:3)
By grace, we are chosen in Christ (Romans 11:5 So too, at the present time there is a remnant chosen by grace.)
By grace, and nothing of ourselves, we are saved. (Ephesians 2:8 For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God—)
Even the workds that we do are not our own, it is the grace of God (1 Corinthians 15:10 No, I worked harder than all of them—yet not I, but the grace of God that was with me)
We are dead, but for grace (Ephesians 2:5 made us alive with Christ even when we were dead in transgressions—it is by grace you have been saved.)
I'll leave you with this, the closing of Paul to the Thessalonians:
1 Thessalonians 5:28 The grace of our Lord Jesus Christ be with you.
lyrics by John Newton, 1779
Amazing Grace, how sweet the sound
That saved a wretch like me!
I once was lost, but now am found,
Was blind, but now I see.
'Twas grace that taught my heart to fear,
And grace my fears relieved.
How precious did that grace appear
The hour I first believed!
Through many dangers, toils, and snares,
I have already come.
'Tis grace hath brought me safe thus far,
And grace will lead me home.
And when this flesh and heart shall fail,
And mortal life shall cease,
I shall possess within the vail
A life of joy and peace.
When we've been there ten thousand years,
Bright shining as the sun,
We've no less days to sing God's praise
Than when we first begun.
