Ecclesiastes 2:17-25
So I hated life, because the work that is done under the sun was grievous to me. All of it is meaningless, a chasing after the wind.
I hated all the things I had toiled for under the sun, because I must leave them to the one who comes after me. And who knows whether he will be a wise man or a fool? Yet he will have control over all the work into which I have poured my effort and skill under the sun. This too is meaningless.
So my heart began to despair over all my toilsome labour under the sun. For a man may do his work with wisdom, knowledge and skill, and then he must leave all he owns to someone who has not worked for it. This too is meaningless and a great misfortune. What does a man get for all the toil and anxious striving with which he labours under the sun?
All his days his work is pain and grief; even at night his mind does not rest. This too is meaningless.
A man can do nothing better than to eat and drink and find satisfaction in his work. This too, I see, is from the hand of God, for without him, who can eat or find enjoyment?
Matthew 6:25-34
“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 important than food, and the body more important than clothes?
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?
Who of you by worrying can add a single hour to his life?
“And why do you worry about clothes? See how the lilies of the field grow. They do not labour or spin. Yet I tell you that not even Solomon in all his splendour was dressed like one of these. 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, O you of little faith?
So do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ For the pagans run after all these things, and your heavenly Father knows that you need them.
But seek first his kingdom and his righteousness, and all these things will be given to you as well.
Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own.
