Jews during the days of Christ and the apostles could not enact the death penalty for those violations under Mosaic law which called for it.
Death would have released the spouse from that marriage if the law could have been administered.
Leviticus 19 covered all types of sexual immoralites that called for the death penalty in many cases.
Christ permitted divorce and remarriage for
those areas of sexual pornia "fornication."
Moses allowed divorce for any reason and Christ did not repudiate Moses only explained why it was permitted but neither approved of remarriage for those who divorced for just any reason.
To deny Eternal Security is a flat out denial that God will stablish Believers in the Truth ! Its a denial of God's Faithfulness ! 2 Thess 3:3
But the Lord is faithful, who shallstablish you, and keep you from evil.
The word stablish is the greek word sterizo and means:
)to make stable, place firmly, set fast, fix
2) to strengthen, make firm
3) to render constant, confirm, one's mind
First lets establish whom Paul is referring to that God will stablish ! 2 Thess 2:13
13But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:
Paul is writing to those who have been brought to the belief of the Truth by means of the Spirit's sanctification and God's Choice of them !
So Paul is writing to them, that the Lord SHALL make you stable ! What does that mean, to be made stable ? Our English word stable means:
steadfast;not wavering or changeable, as in characterorpurpose;dependable.
Now back to 2 Thess 3:3, also concerning the PROMISE that the Lord shall stablish them, the word stablish is in the future tense which means the certainty of this occurring in the future. So that eliminates the possibility of them becoming unstable or changing from their steadfastness in the future.
Now this Paul says is because of God's Faithfulness, not theirs. So God's faithfulness is at stake if they should loose their steadfastness in the Lord..And those of you who say its possible, you are speaking against the Lord and His Faithfulness !
This faithful LORD GOD of us even said He has a sign of and for this "His Faithfulness". Can God's Faithfulness never become unstable or changing, but his sign of "His Faithfulness" can ... in fact, must?!
The very Church that believes the LORD GOD'S stable and unchangeable Faithfulness, scorns and spurns "The Sabbath of the LORD GOD", yea, WON'T EVEN HAVE IT MENTIONED in the same breath as God's Faithfulness.
