Philippians 4:6 (KJV)  Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. 

Let not your heart and mind be overwhelmed by your cares rather learn to cast your burden upon the Lord. Be specific in your prayer to let the Lord know your concern so that He may undertake to help you.

Because the Lord is all-wise and powerful, He is able to resolve what we cannot by our own strength and wisdom. Therefore, be sure to thank the Lord after giving your cares to Him for answering your prayers.

Philippians 4:7 (KJV)  And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. May the Lord bless His people with His peace through Jesus Christ our Lord. Amen.
