"The question is, 'Have you accepted God’s gift of salvation?' If you have, then you are free from the debt of sin...'
Actually, that is incorrect, the world was freed of its sin debt 2,000 years ago at the cross.
(2 Corinthians 5:19 KJB)
(19) To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.
"Romans 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."
That is also incorrect. That includes works (confessing with your mouth), and can be boasted about, so that shows Paul was writing to Israel, not the body of Christ.
(Ephesians 2:8-9 KJB)
(8) For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
(9) Not of works, lest any man should boast.
By grace are ye saved, not by confessing with your mouth.
Grace and works are anathema.
