“So then, banish anxiety from your heart and cast off the troubles of your body, for youth and vigor are meaningless.” (Eccles. 11:10 NIV) 

God says many times in the Bible not to be anxious

It’s often stated as an outright command not to allow yourself to be anxious, period! That may seem shocking to those who may believe people have no self control over anxiety. But, just think about it, God would never command you to do, or not to do, anything you couldn’t do! The above passage, for instance, is a command to “banish anxiety from your heart.” Here is more from God’s Word on the subject.

Do not be anxious about anything

“Do not be anxious about anything, 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 understanding, will guard your hearts and your minds in Christ Jesus.” (Phil 4:6-7 ESV)

Cast all your anxieties on Him! 

“Casting all your anxieties on him, because he cares for you.” (1 Peter 5:7 ESV) 

Jesus mentions “anxious” three times in the following passage and commands you not to be anxious

“Therefore I tell you, do not be anxious about your life, what you will eat or what you will drink, nor about your body, what you will put on. Is not life more than food, and the body more than clothing? Look at the birds of the air: they neither sow nor reap nor gather into barns, and yet your heavenly Father feeds them. Are you not of more value than they? And which of you by being anxious can add a single hour to his span of life? And why are you anxious about clothing? Consider the lilies of the field, how they grow: they neither toil nor spin, yet I tell you, even Solomon in all his glory was not arrayed like one of these.” (Matt. 6:25-34 ESV)

Therefore

“For God gave us a spirit not of fear but of power and love and self-control.” (2 Tim. 1:7 ESV)
