I remember both Elvis Presley and Willie Nelson singing Your Always On My Mind. The first verse of the song reads

Maybe I didn’t treat you
Quite as good as I should have
Maybe I didn’t love you
Quite as often as I could have
Little things I should have said and done
I just never took the time

You were always on my mind
You were always on my mind

I thought about that song as I was reading Our Daily Bread devotional and read the following statement

What we let into our minds shapes the state of our souls.

Here are a couple of verses that speaks about the christian having the mind of Christ.

Philippians 2:5  Let this mind be in you, which was also in Christ Jesus:

1 Corinthians 2:16 For who hath known the mind of the Lord, that he may instruct him? But we have the mind of Christ.

What if we could sing, with conviction and praise to God,  Lord, You’re Always On My Mind…You’re Always On My Mind.

I was doing some research and found this song by Misty Edwards..Always on my mind..
