music in my heart?

"Sing to the Lord with thanksgiving;
make music to our God on the harp.
He covers the sky with clouds;
he supplies the earth with rain
and makes grass grow on the hills.
He provides food for the cattle
and for the young ravens when they call.
His pleasure is not in the strength of the horse,
nor his delight in the legs of a man;
the LORD delights in those who fear him,
who put their hope in his unfailing love.
Psalm 147:7~11

I have been convicted about my heart. There was no singing with thanksgiving and music to my God in my heart. I don't know when was the last time I truly made music for who God is in my heart. My heart has been very cold and just hanging in this reality of my life. I was sad that I was focus on what I feel and what I have instead who God is and what kind love he has been pouring out to me. It's crazy that the Lord delights in us who fear him, who put our hope in his unfailing love. When was the last time I made music in my heart for his unfailing love?
