1 Corinthians 15:58 Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
When Daniel and his three Jewish friends became captives of the pagan-worshiping Babylonians Empire, they purposed in their hearts to serve the Lord whatever the cost.
It would have been easy to say, "Well, it's all right, everyone else is bowing to the idol." Or "We had better do what the king says." Or "We'll obey the king outwardly, but we'll keep our faith to ourselves."
When the king threw Daniel in the den of lions, they didn't hurt him. When the king threw Daniel’s three friends in the fiery furnace they were not burned or even scorched. What a mighty witness to those pagan worshippers.
Christians need this same level of determined commitment to God. Then we can say, “Stand back and see the glorious handiwork of God Almighty.”
