“spiritually dead” is an invention of man. It is NOT biblical teaching, anywhere. PERIOD!
It is a biblical teaching. Period.
Those who bury their dead are just as dead as the ones they bury because they have been sentenced to return to the same ground.
That is clearly not what is being stated. "Dead" is used with two different meanings--physically and spiritually. You're ignoring the obvious contrast of those who want to follow Jesus and so have life:
Luk 9:60 And Jesus said to him, “Leave the dead to bury their own dead.
But as for you, go and proclaim the kingdom of God.” (ESV)
It is those who
don't follow him that are the first "dead" he is speaking of. Jesus also mentions both the spiritually and physically dead here:
Joh 5:21 For as the Father raises the dead and gives them life, so also the Son gives life to whom he will.
Joh 5:22 For the Father judges no one, but has given all judgment to the Son,
Joh 5:23 that all may honor the Son, just as they honor the Father. Whoever does not honor the Son does not honor the Father who sent him.
Joh 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me
has eternal life. He does not come into judgment, but
has passed from death to life.
Joh 5:25 “Truly, truly, I say to you, an hour is coming, and is now here,
when the dead will hear the voice of the Son of God, and those who hear will live.
Joh 5:26 For as the Father has life in himself, so he has granted the Son also to have life in himself.
Joh 5:27 And he has given him authority to execute judgment, because he is the Son of Man.
The above speaks of spiritual resurrection from sin.
Joh 5:28
Do not marvel at this, for an hour is coming when all who are in the tombs will hear his voice
Joh 5:29 and come out, those who have done good to the resurrection of life, and those who have done evil to the resurrection of judgment. (ESV)
This clearly speaks of physical resurrection.
That's why Paul also says:
Eph 2:1
And you were dead in the trespasses and sins
Eph 2:2
in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience—
Eph 2:3 among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.
Eph 2:4 But God, being rich in mercy, because of the great love with which he loved us,
Eph 2:5
even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—
Eph 2:6
and raised us up with him and seated us with him in the heavenly places in Christ Jesus, (ESV)
Paul's point is clearly that believers once "were dead," but are not any longer. And that is despite still being in the process of physically dying, so we know he isn't saying that we were physically dead.
Sorry friend, but I believe God, not man who thinks he knows better than God and adds his own words and ideas to the scripture.
This is a poor argument. You
assume that what you believe is from God and that anyone who disagrees with you doesn't believe God. Yet, anyone could make that claim, so that gets us nowhere. You essentially believe yourself.
