Romans 15:13a
I pray that the God who gives hope will fill you with much joy and peace while you trust in Him.
Psalm 131:2
But I am calm and quiet, like a baby with its mother. I am at peace, like a baby with its mother.
Serenity is not acceptance, it is complete trust.
Every time I read the verse in Psalm 131, I can actually feel my body relax.
