Sinning (ex) in-laws - Divorce Minister
Fathers, do not exasperate your children; instead, bring them up in the training and instruction of the Lord.
-Ephesians 6:4, NLT
I wonder how many of us had interfering in-laws in our marriages that ended with our Cheater.
Instead of instructing their own child in the ways of the Lord, they tried to control their son or daughter-in-law, the faithful party. To them, their child was the wronged party and the infidelity was only an insignificant side issue. (Sadly, many pastors and counselors would be willing to back them up in spreading this LIE.)
Maybe they treated your offer of reconciliation–provided evidence of repentance–with your Cheater with the same contempt the Cheater treated it?
If they supported their child–i.e. your Cheater–divorcing you, they are complicit in sin. They will have to answer for this sin before God (see 2 Corinthians 5:10).
Honestly, I think natural consequences are pretty brutal punishments themselves. Those former in-laws will forever have to live with the truth that they help destroy their child’s marriage and defied God (see Mt 19).
