But this is the covenant that I will make with the house of Israel after those days, saith the LORD; I will put my law in their inward parts, and in their heart will I write it; and I will be their God, and they shall be my people:
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.
