We get stuck in habitual thinking, and when we are finished with something that requires our immediate attention to something in detail and our minds relax, so to speak, they can go to someplace by habit that is not a good place to be. I wish I were better at being thankful for small things and concentrate on that more, and practicing that can help get us out of a habitual rut. But one place I always come to is remembering that my Father is in control and being thankful for and resting in that.
It’s not our perfect love! It is our Father’s, and he only does what is good for both him and us. The most frequent mandate in the Bible is “Don’t be afraid” or one of its several variations: “Fear not!", Be anxious for nothing”, “Fret not”, etc. So whenever I catch myself being anxious about ANYTHING, I can go crawl up on Father’s lap even when court is in session in the throne room, so to speak, and his strong arms will comfort me and shield me.
