So dead does mean dead then. Good. If you did distinguish between the two you and yours would quit making the same category error. You can be physically alive, yet devoid of Spiritual life.
But spiritual death is not physical death nor is your view of it correct

Draw near to God
James 4:8-10
Draw near to God, and He will draw near to you. Cleanse your hands, you sinners, and purify your hearts, you double-minded. / Grieve, mourn, and weep. Turn your laughter to mourning, and your joy to gloom. / Humble yourselves before the Lord, and He will exalt you.
return to the Lord

Let the wicked man forsake his way and the unrighteous man his thoughts; let him return to the LORD, that He may have compassion, and to our God, for He will freely pardon.
Choose to serve God
Joshua 24:15–22 (LEB) — 15 But if it is bad in your eyes to serve Yahweh, choose for yourselves today whom you want to serve, whether it is the gods that your ancestors served beyond the river, or the gods of the Amorites in whose land you are living; but as for me and my household, we will serve Yahweh.”
16 And the people answered and said, “Far be it from us that we would forsake Yahweh to serve other gods,
17 for Yahweh our God brought us and our ancestors from the land of Egypt, from the house of slavery, and did these great signs before our eyes. He protected us along the entire way that we went, and among all the peoples through whose midst we passed.
18 And Yahweh drove out all the people before us, the Amorites who live in the land. We will serve Yahweh, for he is our God.”
19 But Joshua said to the people, “You cannot serve Yahweh, for he is a holy and jealous God; he will not forgive your transgressions or your sins.
20 If you forsake Yahweh and serve foreign gods, he will turn and bring disaster to you; he will destroy you after he has done good to you.”
21 And the people said to Joshua, “No, we will serve Yahweh.”
22 And Joshua said to the people, “You are witnesses against yourselves that you have chosen for yourselves to serve Yahweh.” And they said, “We are witnesses.”
Choose life
Deuteronomy 30:11–20 (LEB) — 11 “
For this commandment that I am commanding you today is not too wonderful for you, and it is not too far from you. 12 It is not in the heavens so that you might say, ‘Who will go up for us to the heavens and get it for us and cause us to hear it, so that we may do it?’ 13 And it is not beyond the sea, so that you might say, ‘Who will cross for us to the other side of the sea and take it for us and cause us to hear it, so that we may do it?’ 14
But the word is very near you, even in your mouth and in your heart, so that you may do it. 15 “
See, I am setting before you today life and prosperity and death and disaster; 16 what I am commanding you today is to love Yahweh your God by going in his ways and by keeping his commandments and his statutes and his regulations, and then you will live, and you will become numerous, and Yahweh your God will bless you in the land where you are going. 17 However, if your heart turns aside and you do not listen and you are lured away and you bow down to other gods and you serve them, 18 I declare to you today that you will certainly perish; you will not extend your time on the land that you are crossing the Jordan to go there to take possession of it. 19 I invoke as a witness against you today the heaven and the earth: life and death I have set before you, blessing and curse.
So choose life, so that you may live, you and your offspring, 20
by loving Yahweh your God by listening to his voice and by clinging to him, for he is your life and the length of your days in order for you to live on the land that Yahweh swore to your ancestors, to Abraham, to Isaac, and to Jacob, to give to them.”
Isaiah 55:3 (LEB) — 3 Extend your ear, and come to me! Listen so that your soul may live, and I will make an everlasting covenant with you, the enduring proofs of the mercies shown to David.
