Psalm 121 and Part of 139

I lift up my eyes to the hills --
where does my help come from?
My help comes from the LORD,
the Maker of heaven and earth.

He will not let your foot slip --
He who watches over you will not slumber;
indeed, He who watches over Israel
will neither slumber nor sleep.

The LORD watches over you --
the LORD is your shade at your right hand;
the sun will not harm you by day,
nor the moon by night.

The LORD will keep you from all harm --
He will watch over your life;
the LORD will watch over your coming and going
both now and forever more.

It seems so easy to forget that God is completely concerned about my life and what is going on in it. He knows the problems and I have and exactly the situations I am in the middle of. I mean, seriously, He never sleeps. He knows all the hairs on my head. His plans for me were in place ages before I was even born. He cares about me so much that the number of thoughts He has about me are numberless...So why do I get worried about things so often? It seems easy and obvious when I think on these things. Thanks, God, for the reminder.
