Daniel 3:18

But if not - That is, "if he should "not" deliver us; if it should "not" occur that he would protect us, and save us from that heated oven: whatever may be the result in regard to us, our determination is settled."

Be it known unto thee, O king, that we will not serve thy gods ... - This answer is firm and noble. It showed that their minds were made up, and that it was with them a matter of "principle" not to worship false gods. The state of mind which is denoted by this verse is that of a determination to do their duty, whatever might be the consequences. The attention was fixed on what was "right," not on what would be the result. The sole question which was asked was, what "ought" to be done in the case; and they had no concern about what would follow. True religion is a determined purpose to do right, and not to do wrong, whatever may be the consequences in either case. It matters not what follows - wealth or poverty; honor or dishonor; good report or evil report; life or death; the mind is firmly fixed on doing right, and not on doing wrong. This is "the religion of principle;" and when we consider the circumstances of those who made this reply; when we remember their comparative youth, and the few opportunities which they had for instruction in the nature of religion, and that they were captives in a distant land, and that they stood before the most absolute monarch of the earth, with no powerful friends to support them, and with the most horrid kind of death threatening them, we may well admire the grace of that God who could so amply furnish them for such a trial, and love that religion which enabled them to take a stand so noble and so bold.

3:18 But if not - It was therefore all one to them, which way God would honour himself; they were resolved to suffer rather than sin, and leave the cause to God. Indeed if God be for us, we need not fear what man can do unto us. Let him do his worst. God will deliver us either from death, or in death.
