We read this in 2 Timothy 1:9 Who hath saved us, and called us with a holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the word was.
Ephesians 2:8 For by grace are you saved through faith; and that not of yourselves: it is a gift of God.
Titus 2: 11 For the grace of God that bringeth salvation hath appeared to all men. ( People of different nation's ) this is not Gods grace providing salvation for all mankind’s unlimited atonement. God's grace in salvation is limited only to those he hath chosen, elected in old eternity. To all who's names are written in the Lambs book of Life.
Romans 8: 28 And we know that all things work together for good to them that love God, to them that are called according to his purpose. 29 For whom he did foreknow he also did predestinate to be conformed to the image of his Son, that he might be the first-born among many brethren. 30 Moreover whole he did predestinate, them he also called: and whom he called them he also justified: and whom he justified, them he also glorified.
To all who believe the gospel of Jesus Christ and was crucified as the subsitude for their sins; we read in Acts 13:48 as many as were ordained to eternal life believed.
Our salvation is by God's purpose and grace. Have a great day.
