Serenity
noun
1. The quality or state of being serene; clearness and calmness; quietness; stillness; peace.
2. Calmness of mind; eveness of temper; undisturbed state; coolness; composure.

Philippians 4:6–7 speaks of the inner peace that comes from fully trusting God to meet all our needs: “Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.”

I find that when I am fully trusting God with every aspect of my life, that is when I have true serenity... it is only then that I can truly be cool, calm, and collected...at peace with myself and what God is doing in my life.
