When we ask God for peace but still feel anxious.
Summary
The sermon emphasizes that true peace comes not from asking God for it, but from trusting His character and the promise that He maintains perfect peace for those whose minds are stayed on Him. This is illustrated by Isaiah 26:3, highlighting that God's trust in us is the foundation for His peace in us. The practical takeaway is to shift from doubting to actively focusing our minds on God to experience His promised peace.
