Well, Moses was dead before Joshua asked God to stop the setting of the sun and long dead before Shadrach, Meshach and Abednego came through the fiery furnace. In other words, Joel Osteen doesn't know his Bible.
From the numbers verse:
23 The Lord answered Moses, “Is the Lord’s arm too short? Now you will see whether or not what I say will come true for you.”
You seem to be saying that since the boys met the firey furnace after Moses was dead, that any mention of subsequent miracles are off limits when analyzing this or any other particular ancient bible verse.
God’s message to Moses means that his power is not just for today. But for all eternity. I don’t think you would disagree with that statement.
God’s power is not just for the moment at hand, which seems to be what you are saying. God’s words to Moses applies to everyone in the future, including the three in the furnace in the future, doesn’t it?
If you don’t care for Joel’s messages, just don’t turn on the program and let God, and not man, sort it out.
