Here is something to think about. I go back and read it often when I get in situations like you are in right now.
THE REAL ENEMY
Main Scripture: Isaiah 49:8-26
Are you angry at your spouse? Are you tired of all the circumstances? When we say we are praying and waiting for our spouse to come home, we often forget who is the enemy. When we talk to family and friends, we often blame our spouse for everything that has happened.
Your spouse is a prisoner! Visualize an enemy coming into your home and taking your spouse as a hostage. While your spouse is a hostage, the enemy brainwashes your mate and has him or her do things that are so unlike that person you married. He does not even care about the children or family which once were so important!
For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Ephesians 6:12
Believe in the Lord God you serve. If you had been brainwashed or deceived, would you not want your spouse or family praying and interceding in your behalf? Why can we not wait? Is it our own selfishness? Is it truly our lack of faith in whom we believe?
With man this is impossible, but not with God; all things are possible with God. Mark 10:27
HE CAME TO SET THE CAPTIVES FREE
This is something else that I was told. Yes, your storm will end. Leaving behind the calm presence of the Holy Spirit. Don't give up before your storm passes by.
Don't try to figure out what you are going to say to your husband and when. Let the Lord be your lead. He is not running from you or your son. He is trying to run from himself. You have no idea what is happening on the inside of him or what he is going through personally.
All you know is what you are feeling and what he has done to you guys. That is all that you can see at this time as well. I have no idea why he up and ran like he did, but something scared him and it was something big. There is no way to know what he is feeling or thinking at this time and there is no way to know what he is doing with his life until he decides to share it. I think that is the most frustrating part because you don't understand where it came from.
I would not want to be in your husband's shoes for anything because there is something awful going on inside of him. He may not show it to you, but there is something there and it is big.
