Phil you vascilate so rapidly between anger and despair that the only person I can think of that did it any faster than you was me.
So I'm not just whistling dixie here, I'm telling you what I know.
You are not quiet. And I guarantee you that even if your mouth is closed, your body language is screaming. If it were not the case you'd be further outta the boat walking on the water by now thinking to heck with her, I need to get to HIM.
You are coming upon a crossroads. There will be two paths from which you can choose.
One leads to bitterness and you will take that one if you throw your wife away - when it is your God-given responsibility to stand in the gap for her - instead finding a place of understanding and compassion in your heart, through HIM, that will allow you to walk this walk with some modicum of dignity and peace.
The other path you may have heard of. It is the one He says to choose.
It leads to life.
Phil, the faith that you DO possess and this present state of your family is not a coincidence. The enemy is at work, but he is at work in YOU. I'm going to say something to you now that is harsh - and likely to offend you - but I'm telling you what I recognize...your faith is "lukewarm", Phil. I know this because when held against the hottest flames mine was, too. And so the tests come to establish you. How you react determines where your faith takes you, or if it leaves you.
