John 14:1, Do not let your hearts be troubled. Trust in God; trust also in me, says the Lord.
Matthew 6:25–34 says, Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more important than food, and the body more important than clothes? Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? Who of you by worrying can add a single hour to his life? And why do you worry about clothes? See how the lilies of the field grow. They do not labor or spin. Yet I tell you that not even Solomon in all his splendor was dressed like one of these. If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will He not much more clothe you, O you of little faith? So do not worry, saying, What shall we drink? or What shall we wear? For the pagans run after all these things, and your heavenly Father knows that you need them. But seek first His kingdom and His righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow; for tomorrow will worry about itself, Each day has enough trouble of its own.
Jesus teaches us about one of the most dangerous weaknesses in our spiritual lives, one which threatens to overcome many people in His Kingdom.
What is the weakness Jesus is talking about? Read Matthew 6:25.
The simple method Jesus gives for overcoming worry in our lives is to trust in and serve our heavenly Father wholeheartedly; He then promises to care for us. Jesus gives us two examples of this care, both taken from nature. See verses 26 and 28, Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? And why do you worry about clothes? See how the lilies of the field grow. They do not labor or spin.
What Jesus is saying here and today: worry consists of the fear of the future. However, we can confidently leave the future in the hands of God, because He is Sovereign and has all power. He is also loving and takes care of us in the same way that He does of the birds and the flowers.
See what Paul says in Philippians 4:6–7, Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus.
Another word of peace is serenity. As children of God, we should be serene people, not overcome by worry and anxiety.
