At peace.
And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
There is no fear in love. But perfect love drives out fear…
It’s not our perfect love! It is our Father’s, if you belong to him, 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.
“Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light" - Jesus
I was at peace, even at the first, when this happened, not knowing how imminent my death or pain might be: Nephrectomy, and during this: High Water.* (I can get frazzled sometimes when hurried, though.
