Another strategy for avoiding worry if you are a Christian ...
4 Remember God’s love for you
When you meditate on God’s love for you in the Lord Jesus Christ: choosing you before the foundation of the world to share in his eternal kingdom; sending his own son to die for you - to deal with your sin and to clothe you with his righteousness … When you think about all these things and the other good that flows from this, how can you doubt that God loves you and wants the best for you? God will supply everything you need.
... your heavenly father knows that you need [food, drink, clothes, etc.]. (Matthew 6:32)
And you are precious to him.
Are you not much more valuable than [the birds of the air]? (Matthew 6:26)
Yes, times might be difficult, but the promise of Romans 8:28 still stands:
You know that in all things God works for the good of those who love him, who have been called according to his purpose.
For the LORD God is a sun and shield; the LORD bestows favour and honour; no good thing does he withhold from those whose walk is blameless. (Psalm 84:11)
Praise the LORD, O my soul; all my inmost being, praise his holy name.
Praise the LORD, O my soul, and forget not all his benefits -
who forgives all your sins and heals all your diseases,
who redeems your life from the pit and crowns you with love and compassion,
who satisfies your desires with good things so that your youth is renewed like the eagle's.
The LORD works righteousness and justice for all the oppressed.
He made known his ways to Moses, his deeds to the people of Israel:
The LORD is compassionate and gracious, slow to anger, abounding in love.
He will not always accuse, nor will he harbour his anger forever;
he does not treat us as our sins deserve or repay us according to our iniquities.
For as high as the heavens are above the earth, so great is his love for those who fear him;
as far as the east is from the west, so far has he removed our transgressions from us.
As a father has compassion on his children, so the LORD has compassion on those who fear him;
for he knows how we are formed, he remembers that we are dust.
As for man, his days are like grass, he flourishes like a flower of the field;
the wind blows over it and it is gone, and its place remembers it no more.
But from everlasting to everlasting the LORD's love is with those who fear him, and his righteousness with their children's children-
with those who keep his covenant and remember to obey his precepts.
The LORD has established his throne in heaven, and his kingdom rules over all.
Praise the LORD, you his angels, you mighty ones who do his bidding, who obey his word.
Praise the LORD, all his heavenly hosts, you his servants who do his will.
Praise the LORD, all his works everywhere in his dominion.
Praise the LORD, O my soul. (Psalm 103)
