Daniel 3:18

“But if not, etc.] If our God does not think fit to exert his power, and deliver us, which we are well assured he is able to do; if it is not his will, we are content, we are resigned unto it: be it known unto thee, O king, that we will not serve thy gods, be it as it will, whether we are delivered or not; we are not sure of the one, but we are at a point as to the other: nor worship the golden image which thou hast set up; come life, come death, we are ready; we had rather die than sin: they were all of one mind, and agreed in this matter; a noble instance of spiritual fortitude and courage!”

“But if not, &c.--connected with Dan 3:18. "Whether our God deliver us, as He is able, or do not, we will not serve thy gods." Their service of God is not mercenary in its motive. Though He slay them, they will still trust in Him (Job 13:15). Their deliverance from sinful compliance was as great a miracle in the kingdom of grace, as that from the furnace was in the kingdom of nature. Their youth, and position as captives and friendless exiles, before the absolute world potentate and the horrid death awaiting them if they should persevere in their faith, all enhance the grace of God, which carried them through such an ordeal.”

“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…”

“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. Daniel 3:20”
