I really encourage you to get the book...It is well worth it especially for this chapter in the book! I am only going to type of a few of the things that stuck out.
2 Corinthians 2:10
To whom ye forgive any thing, I [forgive] also: for if I forgave any thing, to whom I forgave [it], for your sakes [forgave I it] in the person of Christ;
Forgiveness MUST happen, or a successful marriage won't!
And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due unto him.
Torture is prison. When you think of unforgiveness, this is what should come to your mind, for Jesus said , "So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses."
When you forgive another person, you are not turning them loose. You're just turning them over to God, who can be counted on to deal with them his way. You're saving yourself the trouble of scripting any more arguments or trying to prevail in this situation. It's not about winning and losing anymore. It's about freedom. It's about letting go. That's why you often hear people who have genuinely forgiven say, "It felt like a weight being lifted off my shoulders."
[Let] love be without dissimulation. Abhor that which is evil; cleave to that which is good.
How do we do this?
You release your anger and the responsibility for judging this person to the Lord.
Dearly beloved, avenge not yourselves, but [rather] give place unto wrath: for it is written, Vengeance [is] mine; I will repay, saith the Lord.
How do you know you've done it?
You know it when the thought of their name or the sight of their face- rather than causing your blood to boil- causes you to feel sorry for them instead, to pity them, to genuinely hope they get this turned around.
1 Corinthians 13:5
Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;
WHATEVER YOU HAVEN'T FORGIVEN IN YOUR MATE, FORGIVE IT TODAY. LET IT GO. JUST AS WE ASK JESUS TO "FORGIVE US OUR DEBTORS" EACH DAY AS WELL. UNFORGIVENESS HAS BEEN KEEPING YOU AND YOUR SPOUSE IN PRISON TO LONG. SAY FROM YOUR HEART, " I CHOOSE TO FORGIVE."
