The third chapter of first Peter is about how wives and husbands should interact with each other.  You can read that part yourself and decide what you need to work on.  Chapter four is general instructions.

Peter 5:6-8  "Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time:  Casting all your care upon him; for he cares for you.  Be sober, be vigilant; because your adversary the devil, as a roaring lion walks about, seeking whom he may devour:

The roaring of the male lion scares prey to move toward the pack of females who are ready to make the kill.  They used to think the males had no part in the hunt.  But further study showed that he put fear in the hearts of the prey and caused them to move away from him and into a trap.

The devil himself is the roaring lion who is out to move humans into a trap.  Peter knew about lions.  He used this analogy to explain the absolute necessity to be vigilant.  The devil wants to eat you.

But God, with his mighty hand desires to exalt you.  He requires two things.  You must be humble, and you must cast all your care on Him.

Lately I have been burdened with cares.  As Ken gets weaker,  I can no longer lift him.  But God is watching.  He knows my needs and one at a time my four children have taken turns staying with me.  Yesterday, Pat, my eldest, decided to move in Monday through Fridays for awhile.  Her husband Tom  understands.  He takes care of his parents.  On the weekends, I have a helper that comes in.

God is really good.  I have four children that want to be the ones to take care of their father.  We will do this.  For awhile.  For a while longer.  Ken has no idea how to give up, or quit.  He just keeps on keeping on.  I really don't know how he does it.  God must have a plan that He hasn't shared with me yet.
