Marriage Joined By God
Marriage is still honourable even in this end time period but there is no reward in heaven for being in a relationship that is not joined by God, and most marriages are not joined by God.
Also, there is no reward for having a quiver full of unsaved biological children.
On the contrary being married through the backdoor or having a large number of unsaved children can be the cause for ineligibility to be included in the rapture of the Ekklesia.
