“Do not store up for yourselves treasures on earth, where moths and vermin destroy, and where thieves break in and steal. But store up for yourselves treasures in heaven, where moths and vermin do not destroy, and where thieves do not break in and steal. For where your treasure is, there your heart will be also.
“The eye is the lamp of the body. If your eyes are healthy,[a] your whole body will be full of light. But if your eyes are unhealthy,[b] your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness!
“No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money.
“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? 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? Can any one of you by worrying add a single hour to your life[c]?
“And why do you worry about clothes? See how the flowers of the field grow. They do not labor or spin. Yet I tell you that not even Solomon in all his splendor 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—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.
Recently I was noticing what could be a tie between Jesus’s words here in the Sermon on the Mount about not being able to be devoted to both God and money, and the need therefore, we might say, to trust God for our material needs. What we’re to be preoccupied with is devotion to God, seeking God’s kingdom and righteousness first.
I can’t help but think of Ahaz, who seems pious in his claim of not wanting to put the Lord to the test, but in reality suffered from his deficiency in trusting God, so that God was perhaps trying to help him trust God by encouraging him to ask for a sign as to whether or not God’s word at that time would come true or not (Isaiah 7).
The 2011 NIV’s rendering of Proverbs 3:5-6 is interesting and suggestive in understanding the tie to unbelief and idolatry:
Trust in the Lord with all your heart
and lean not on your own understanding;
in all your ways submit to him,
and he will make your paths straight.[a]
The idea of submitting to God is the result of acknowledging him in all our ways. To acknowledge him involves seeking his will and doing it.
Back to Jesus’s words. They are words of exhortation and encouragement, to trust the Father for his provision. And they do seem tied to what preceded, to not be taken up with money, since one cannot be devoted to money and God. It is either one or the other.
So one form of idolatry, or danger falling into it is simply to fail to trust God, to have faith in him. We then put our faith elsewhere, maybe in a mix of things. Idolatry. But God wants to help us learn to trust in him, an essential part of devotion to him, in and through Jesus.
