nope, repent of your sins is works according to
Jonah 3:10. and we are not saved by works. Jesus did all the work, we just believe on him. Jesus paid it all..repent means change of mind. not "of your sins" those verses say nothing about repeting of sins for eternal life, salvation.
Jonah doesn’t declare as “works” the NT Greek word “repentance” or “repent” (
metanoeo from
meta = with, among +
noeo = to think, exercise the mind <> from
nous = mind; cf
metanoia) means to have another mind.)
The Hebrew in
Jonah 3:10 is not a reference to “change of mind” Greek metanoeo, but the Hebrew of
Jonah 3:10 is a change in direction of one’s actions from something, meaning they turned from wicked actions.
So, Jonah is not applicable as a limiting qualification or rebuttal of any NT verses invoking the Greek word metanoeo “repent” and/or “repentance.”
Yet, this doesn’t weaken or strengthen your claim believing in Jesus is sufficient to be saved. This is, as a general proposition, true and finds support from Paul. “[T]hat is, the word of faith which we are preaching, 9 [
f]that if you confess with your mouth Jesus
as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart
a person believes, [
g]resulting in righteousness, and with the mouth he confesses, [
h]resulting in salvation.” Romans 10.
Yet, the NT is inundated with verses of the necessity of “repentance.” The NT verses using metanoeo are rationally understood to “think” or to “change” one’s “thinking” at least in regards to Jesus. More explicitly, to direct one’s thoughts to understand and accept Jesus as the Son of God, who died for our sins, and was resurrected from the dead and lives forever more.
From this proper understanding of the Greek for “repent” and “repentance” in the NT, repent and repentance is required for salvation. Indeed, Paul’s verse of, ““[T]hat is, the word of faith which we are preaching, 9 [
f]that if you confess with your mouth Jesus
as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart
a person believes, [
g]resulting in righteousness, and with the mouth he confesses, [
h]resulting in salvation.”, is consistent with and reflective of a subject who has engaged in “metanoeo” where the person is
thinking of Jesus as Lord, raised from the dead, and now “believes.”
“Therefore
repent and return, so that your sins may be wiped away…”
Acts 3:19
“The Lord is not slow about His promise, as some count slowness, but is patient toward you, not wishing for any to perish but for all to come to
repentance." (
2 Peter 3:9)
Peter
said to them, “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; Acts 3:38
“God is now proclaiming to mankind that all people everywhere are to repent, 31 because He has set a day on which He will judge [
v]the world in righteousness [
w]through a Man whom He has appointed, having furnished proof to all people [
x]by raising Him from the dead.” Acts 17:30
*not exhaustive list of repent/repentance in NT*
So, the NT does invoke the Greek word “metanoeo” our English repent/repentance, which means in Greek “to think, exercise the mind <> from
nous = mind; cf
metanoia) means to have another mind,” as necessary for salvation.
