One of the great truths of the Christian life is that you and I can know the peace of God in our lives because we have peace with God. As believers, we need not live our lives without God's peace.
Are you worried right now about anything? Finances? Kids? Marriage? Job security? Your health? What somebody said about you? How a situation is going to turn out?
If you are worried about anything, here are some instructions for you found in Philippians 4:6-7,
Be anxious for nothing, but in everything [that means in every circumstance] 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.
Talk to the Lord about your problems, offering thanks along with your requests. He promises to give you peace if you will.
Let me leave you with these words from Dr. Stanley Jones:
"I am inwardly fashioned for faith, not for fear. Fear is not my native land; faith is. I am so made that worry and anxiety are sand in the machinery of life; faith is the oil…. A Johns Hopkins University doctor says, ‘We do not know why it is that worriers die sooner than non-worriers, but that is a fact.' But I who am simple of mind think I know; We are inwardly constructed…for faith and not for fear. God made us that way. To live by worry is to live against reality."
