Romans 10:9-10
9 that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. 10 For with the heart one believes unto righteousness, and with the mouth confession is made unto salvation.
Pisteou for believe I see.
Ephesians 2:8-10
8 For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, 9 not of works, lest anyone should boast. 10 For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
Pistis used here.
Why the difference?
Anyway faith in action.
Created to good works.
Saved by faith that do them.
Not saved by said works.
If a person does not confess Jesus as Lord and believe he was raised from the dead.
Then good works for Jesus will not follow.
