"He gave them their own desire"

I write this second preface to consider God's nature to give men their own desire. Many have come to the conclusion that it is God's will for them to remarry, because God provided them a new wife. If we are stubborn and harden our hearts, many times God will give us that which we seek, to our detriment.

"And they tempted God in their heart
by asking meat for their lust.

So they did eat, and were well filled:
for he gave them their own desire;

they were not estranged from their lust:
but while their meat was yet in their mouths,
the wrath of God came upon them,
and slew the fattest of them,
and smote down the chosen men of Israel."

Psalm 78:18,29-31

When it comes to divorce and remarriage, if you are determined to remarry against God's will, according to how He has revealed Himself throughout history, He will most likely allow you to have your own desire. Actually, I believe the reason God put the Matthew 19:9 exception was to expose the condition of people's hearts. Jesus prefaced Matthew 19:9 by saying:

"He saith unto them, Moses
because of the hardness of your hearts
suffered you to put away your wives:
but from the beginning it was not so."
Matthew 19:8

So, if you are using the Matthew 19:9 exception as an excuse to remarry, you are publicly showing the hardness of your heart to God's perfect will for marriage as revealed in Matthew 19:5-6.

A few verses related to the character of God "to give them their own desires" are given below:

"...God also gave them up to uncleanness, through the lusts of their own hearts, to dishonor their own bodies between themselves..."
Romans 1:24

"For this cause God gave them up unto vile affections..."
Romans 1:26

"...God gave them over to a reprobate mind,
to do things which are not convenient;"
Romans 1:28

"And for this cause God shall send them strong delusion,
that they should believe a lie: that they all might be damned
who believed not the truth, but had pleasure in unrighteousness."
2 Thessalonians 2:11-12
