You're entire post is false because you based it on God being 'pro-divorce' and he isn't and never has been.<quoted text>
If God isn't "pro-heavenly divorce" then all marriages would be eternal marriages. God told Peter "what you bound on earth will be bound in heaven", and if every marriage is suppose to be lived according to the practice of joining of "one flesh" then God breaks his own rule by saying only some would be eternal. If Peter was suppose to be performing eternal marriages, he would have at least built endowment houses, but he did not. He didn't even talk about the need for one. This would be doubly true if those marriages were essential to our place in God's kingdom. A person is only under the law of marriage while he lives, that is clear from Romans 7.
There is a difference between God allowing something because he is not in opposition to it and, God allowing something because he is not obviously in favour of it. God was never in favour of divorce. God never instituted a law for divorce because he favoured divorce. Do you not remember what the OT stated about God's opinion of divorce and why he allowed Moses to make a law for it?
