I mean SAVED, as in serving Jesus!
So, an abusive husband or wife who is being unbelieving is serving Jesus now, is he?
The word used for 'saved' in Acts 16:31 is "Sozo", and it is often used as a means of PHYSICALLY being 'saved'.
Here's are some examples;
Mathew 8:25
And his disciples came to him, and awoke him, saying, Lord,
save us: we perish.
Mathew 27:40
And saying, Thou that destroyest the temple, and buildest it in three days,
save thyself. If thou be the Son of God, come down from the cross.
Mark 3:4
And he saith unto them, Is it lawful to do good on the sabbath days, or to do evil? to
save life, or to kill? But they held their peace.
Mark 15:31
Likewise also the chief priests mocking said among themselves with the scribes, He
saved others; himself he cannot
save.
Luke 18:42
And Jesus said unto him, Receive thy sight: thy faith hath
saved thee.
John 3:17
For God sent not his Son into the world to condemn the world; but that the world through him might be
saved.
Romans 8:24
For we are
saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?
Romans 10:13
For whosoever shall call upon the name of the Lord shall be
saved.
1 Co 1:21
For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to
save them that believe.
Ephesians 2:5
Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are
saved
Eph 2:8
For by grace are ye
saved through faith; and that not of yourselves: it is the gift of God:
2 Thes 2:10
And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be
saved.
It clearly means becoming a Christian.
Acts 16:31-34 (NKJV)
31 So they said, "Believe on the Lord Jesus Christ, and you will be saved, you and your household." 32 Then they spoke the word of the Lord to him and to all who were in his house. 33 And he took them the same hour of the night and washed their stripes. And immediately he and all his family were baptized. 34 Now when he had brought them into his house, he set food before them; and he rejoiced, having believed in God with all his household.
Is it not obvious by now that 'saved' does not equate to 'Eternal Life' in all instances? Just one more I would like to add, which TOTALLY debunks your thesis;
1 Co 7:16
For what knowest thou, O wife, whether thou shalt
save thy husband? or how knowest thou, O man, whether thou shalt
save thy wife?
