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. ~ Phillippians 4: 6-7
You can't control everything. In fact, we struggle to control even our own desires... much less how something beyond our reach will turn out. And you certainly have no control over how others will respond to you.
But you can control how you respond to the situations around you. Ask God for strength in every situation - so you may represent Him and yourself well today.
