Matthew 6:19-21: 'Do not store up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal. But store up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in or steal. For where your treasure is, there will your heart be also.'
Matthew 6:24: 'No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to one, and despise the other. Ye cannot serve God and mammon.'
Matthew 19:24: '...It's easier for a camel to go through the eye of a needle than for a rich person to get into God's kingdom.'
