No one can serve two masters;
for either he will hate the one and love the other,
or he will hold to one and despise the other.
You cannot serve God and mammon.
For this reason I say to you,
do not be anxious for your life,
as to what you shall eat,
or what you shall drink;
nor for your body, as to what you shall put on.
Is not life more than food,
and the body than clothing?
Look at the birds of the air,
that they do not sow,
neither do they reap,
nor gather into barns,
and yet your heavenly Father feeds them.
Are you not worth much more than they?
And which of you by being anxious can add a single cubit to his life's span?...
Do not be anxious then, saying,
"What shall we eat? or "what shall we drink?"
or "With what shall we clothe ourselves?"
For all these things the Gentiles eagerly seek;
for your heavenly Father knows that you need all these things.
But seek first His kingdom and His righteousness;
and all these things shall be added to you.
Therefore do not be anxious for tomorrow;
for tomorrow will care for itself.
Each day has enough trouble of its own.
Matthew 6: 24-27, 31-34
