No one can serve two masters; for either he will hate the one and love the other, or he will be devoted to one and despise the other. You cannot serve God and wealth. Matthew 6:24
Who is our Master? How can we tell who will be our Master in the days to come? Well, who are we listening to, and who has our ear? If we are listening to the words of God, He will draw us to serve Him. If we are listening and yielding to the word of the devil, we will be drawn to his service. No, we can't do both. That's why the Bible warns us time and time again to listen to what the Spirit is saying. As the kid's song goes, "Oh be careful little ears what you hear." Oh yes, that applies to big ears too.
