"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 comprehension, will guard your hearts and minds in Christ Jesus," (Philippians 4:6,7).
* Within the process of God's peace replacing our anxiety is thankful prayer. Coupled with our intensely urgent crying out for the Lord Jesus' help, there must be confident thanksgiving for His faithfulness. Thanking Him in advance of His answering brings great encouragement and needed perseverance.
* Someone has well said that worry slanders every promise in the Word of God.
By contrast, thanksgiving lays hold of every promise, 'faithing' its truth in spite of adverse circumstances. We can complain, grumble, and worry about our trials; or we can give thanks, take God at His word, and experience His peace.
