Another way that a Christian can avoid worry ...
5 Remember God’s character
Not only does God love you but ...
(a) He is all powerful, he is the one who created you, and he’s sovereign over the universe. He is able to bring his plans to fruition and nothing can thwart him.
(b) He’s also all-knowing and wise. He knows what is best for you.
(c) He’s also omnipresent – present everywhere. You cannot walk away from his protective hand – neither intentionally nor unintentionally.
(d) Finally, remember that God is dependable – he never changes. You can trust him for the future.
Do not be afraid of tomorrow; for God is already there. (Anon)
Humble yourselves, therefore, under God's mighty hand, that he may lift you up in due time. Cast all your anxiety on him because he cares for you. (1 Peter 5:6-7)
