God promises that He will give us a peace that surpasses understanding, but not necessarily a peace that always will give us understanding.
You may be facing a personal crisis right now. Maybe it is a lack of employment. Maybe it is a foreclosure on your home or a loss in your investments. Maybe you have a marriage that is falling apart or a prodigal son or daughter. Maybe you have a life-threatening illness. Maybe you are paralyzed by fear as you think about an uncertain future. So what should you do? The Bible tells us the answer to worry is prayer: "Be anxious for nothing, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God; and the peace of God, which surpasses all understanding, will guard your hearts and minds through Christ Jesus" (Philippians 4:6–7).
I have lived by these words since my son Christopher's departure to Heaven, because I have been hit with harsh reality of it—most notably, his absence. There have been waves of deep sadness that have overwhelmed me at times. So I pray. Sometimes my prayers are not long, but simply a cry out to God: God, help me. Give me strength right now.
And He does. He gives me the strength that I need. It is not necessarily more than I need, but He gives me what I need for what I am facing at the moment.
The psalmist wrote, "From the end of the earth I will cry to You, when my heart is overwhelmed; lead me to the rock that is higher than I" (Psalm 61:2). So when you are feeling overwhelmed, pray. Things will fall into their proper place as God brings about the events of your life according to His perfect will.
