Matthew 6:6-7, 24

But whenever you pray, go into your innermost chamber and be alone with Father God, praying to him in secret. And your Father, who sees all you do, will reward you openly. When you pray, there is no need to repeat empty phrases, praying like the Gentiles do, for they expect God to hear them because of their many words.

“How could you worship two gods at the same time? You will have to hate one and love the other, or be devoted to one and despise the other. You can’t worship the true God while enslaved to the god of money!”
