Salvation is entirely of grace (God’s unmerited favor). It is not something we can add to; we can only receive it by faith.
The Lord has made salvation available by grace alone because nothing we can do could ever earn it. Even our best works are marred by sin. Because this is true, we can’t take any of the credit for our salvation - all the glory goes to God.
Jesus offers Himself to you to be your Savior. All you need to do to be saved is receive Him, look to Him, and trust Him to save you.
