What does the Bible say about standing firm in faith?

In Daniel 3, we see the powerful example of Shadrach, Meshach, and Abednego who stood firm in their faith despite the threat of death. They declared their unwavering trust in God, stating that He was able to deliver them from the fiery furnace, yet they also expressed their readiness to accept the consequences, saying, 'But if not, be it known unto thee, O King, that we will not serve thy gods' (Daniel 3:18). This level of commitment is reflective of a deep faith that prioritizes obedience to God over personal safety.
