Worry paralyzes active faith. When you worry, you assume responsibility for things you were never intended to handle. In Matthew 6:25-34, Jesus states "Do not worry" even about the basic essentials of life. Worry divides our mind between useful and hurtful thinking. Worrying does not change anything (v. 27) except to draw your focus away from God and His faithfulness and righteousness to concerns about the things of life; such as possessions and material goods (v.31). Worry is a choking, harmful emotion that saps your energy and elevates human strength and ingenuity above God's strength and His purposeful plan.
Sources of worry include change, lack of understanding, and lack of control over your life. Worry opens the door to worldliness - preoccupation with the things of this life. Worry is the opposite of faith, suggesting that God cannot be trusted to take care of you or to provide what you need (Phil. 4:19). By worrying, you are actually saying you know better than God. Worry causes fear to crowd out faith.
God has given us His Word because that Word is truth and life!
There is nothing that can separate us from the Love of God who is the great I AM. In the place of anxious thoughts, freely offer thanksgiving from a heart established with trust in God as all sufficient.
Have faith in God and He will fight ALL our battles - even worry! (Matthew 11:22)
