No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.

And Elijah came unto all the people, and said, How long halt ye between two opinions? if the Lord be God, follow him: but if Baal, then follow him. And the people answered him not a word.

COMMENTARY

No man can serve two masters: for either he will hate the one, and love the other
Previously we considered Pharaoh, who wanted the God of the Hebrews to give him reprieve, but also wanted to maintain his control over the Hebrew slaves in direct defiance to that God. As the famous saying goes, though, you cannot ride two horses. If you try, you will only tear yourself, which, tragically is exactly what happened to Pharaoh. By trying to have his cake and eat it, too, he lost his firstborn child.
Many men and women lose the most precious things by trying to clutch to two opposing realities at the same time. Powerful addictions, in fact, often stem from a division of the soul, one where a person genuinely believes in a greater good, and professes it loudly, yet secretly lives a lesser evil on the side. A wedge is gradually driven into the heart, pressing deeper and deeper, until eventually things start to break.

How long halt ye between two opinions? if the Lord be God, follow him: if Baal, follow him.
Each of us only has room for one reality and one master. It is simply not in our nature to thrive so long as we are divided against ourselves. Thus each one of us must choose which reality we will embrace, and then embrace it with all our hearts, letting go of all the rest.
