Do you find yourself anxious when trying to get to sleep? Pray the verse below:
I will lay me down in peace, and take my rest; for you, LORD, only, make me dwell in safety.
Psalm 4:8
And this one:
You keep them in perfect peace whose minds are stayed on you, because they trust in you. Trust in the LORD for ever, for the LORD God is an everlasting rock.
Isaiah 26:3–4
As much as possible, attach your prayers to Scriptures. Soak your petitions in God’s promises. It is our Lord who calms our hearts and brings us rest.

Thanks for the reminder about soaking prayers in scripture… in these days of stress, sometimes we forget about that part, even if we know that God is with us always.
Attaching prayers to Scripture also makes our prayers more fully informed by the biblically revealed character of God and his will for us, which can free us from both worry and wishful thinking!
