I think you need to read your Scripture: yes, they are:
From Exodus 19 (NABRE - USCCB):
3Moses went up to the mountain of God. Then the LORD called to him from the mountain, saying: This is what you will say to the house of Jacob; tell the Israelites:4You have seen how I treated the Egyptians and how I bore you up on eagles’ wings and brought you to myself.
b5Now, if you obey me completely and keep my covenant,
* you will be my treasured possession among all peoples,
c though all the earth is mine.6You will be to me a kingdom of priests,
* a holy nation.
d That is what you must tell the Israelites.7So Moses went and summoned the elders of the people. When he set before them all that the LORD had ordered him to tell them,8all the people answered together, “Everything the LORD has said, we will do.” Then Moses brought back to the LORD the response of the people.
From Deuteronomy 7 (NABRE - USCCB):
6For you are a people holy to the LORD, your God; the LORD, your God, has chosen you from all the peoples on the face of the earth to be a people specially his own.
f
7It was not because you are more numerous than all the peoples that the LORD set his heart on you and chose you; for you are really the smallest of all peoples.
g
8It was because the LORD loved you and because of his fidelity to the oath he had sworn to your ancestors, that the LORD brought you out with a strong hand and redeemed you from the house of slavery, from the hand of Pharaoh, king of Egypt.
h
9
i Know, then, that the LORD, your God, is God: the faithful God who keeps covenant mercy to the thousandth generation toward those who love him and keep his commandments,
j
10but who repays with destruction those who hate him; he does not delay with those who hate him, but makes them pay for it.
11Therefore carefully observe the commandment, the statutes and the ordinances which I command you today.
This only continues in 3 whole chapters - Romans 9-11.
The Church has something on the matter as well:
“THE GIFTS AND THE CALLING
OF GOD ARE IRREVOCABLE”
(Rom 11:29)
