First read what the Word says:
"For the hardness of your heart, he wrote you this precept. But from the beginning of the creation God made them male and female. For this cause shall a man leave his father and mother, and cleave to his wife. And they shall be one flesh so then they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder." Jesus
Read it in its entirety in Mark 10:1-12
"What if God designed marriage to make us holy more than to make us happy?"
By Gary Thomas
Lastly, read my studies:
Marriage is the first institution ordained by God in the Garden of Eden (Genesis) and the last institution ordained by Him when Jesus comes for His bride (Revelation). What do you think is first and last on the enemies list to kill, steal, and destroy? Marriage! Don't fight your spouse when your battle is with the enemy. When it comes to our marriages, don't let Satan win.
I pray this is a timely message. Let me hear from you on future studies you would like to see.
