Do Not Worry25 “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 than food, and the body more than clothes? 26 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? 27 Can any one of you by worrying add a single hour to your life?
28 “And why do you worry about clothes? See how the flowers of the field grow. They do not labor or spin. 29 Yet I tell you that not even Solomon in all his splendor was dressed like one of these. 30 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—you of little faith?

Anxiety is a thief. The combination of fear and uncertainty robs many believers of the peace that the heavenly Father intends for them to have (John 14:27). But anxiety does not fit who we are in Jesus Christ. By putting our faith in Him, we have placed our life in the hands of a sovereign God who wants the very best for His children. What do we have to fear when we trust in Him?
Believing in the Lord doesn't mean that we will never experience uncertainty. What it should means is that we choose to let go of anxiety and instead trust Him to provide for our needs in His time and His way. When we don't, fear and doubt can become entrenched in our thinking and develop into a stronghold. Then Satan will dig in and use every resource he can to build our apprehension. That is what sinful anxiety looks like - a sense of fear that overwhelms faith.
Faith can be besieged and toppled when its foundation is weakened by unbelief. I'm not implying that an anxious believer isn't truly a Christian. However, in saying "I know God is capable of dealing with the problems in my life, but I'm not sure that He will," uncertain saints may look for ways to fix the issue themseles instead of waiting patiently for the Lord to act on their behalf.
Th Lord sees the beginning and the end of every situation that we face. He knows the root of our anxiety, the best way to calm our heart, and how to turn our weeping into joy. He will do all of this without leaving our side, because He loves us deeply and desires to bless us richly.
