Suppose your mouth automatically repeated everything that you thought? Imagine your deepest thoughts on display for everyone to hear and there is nothing you can do to stop it. Not a pleasing idea, is it?
Embarrassment. Shame. Guilt.
The truth is that all of your thoughts are on display, not to other people, but to the Lord of the Universe. Even knowing that God knew all of his thoughts, David rejoiced in this reality. Why, because he had experienced the lovingkindness of his God.
When you go to worship, rid yourself of the pretext that you have any value apart from the mercy of God. Your God knows your thoughts, all of them! But instead of burning wrath pouring out when he looks at you he sees not the ugliness of your thoughts; he sees the beauty of Christ.
Joyfully worship the God who knows your thoughts.
O Lord, you have examined my heart
and know everything about me.
You know when I sit down or stand up.
You know my thoughts even when I’m far away…
How precious are your thoughts about me,[b] O God.
They cannot be numbered!
I can’t even count them;
they outnumber the grains of sand!
And when I wake up,
you are still with me!
Psalm 139:1-2; 17-18
