“But if not, let it be known to you, O king, that we do not
serve your gods, nor will we worship the gold image
which you have set up.”
Daniel 3:18 

In the above verse, Shadrach, Meshach, and Abed-Nego are pressured to deny God, but they choose to be faithful to Him no matter the outcome. Though they trusted God to deliver them, they were determined to remain faithful regardless of the consequences. Why were Shadrach, Meshach, and Abed-Nego so confident? They new that it was more important to follow God and have eternal life than to live and betray God.

Knowing that the furnace could never kill their souls, the three young Jewish men held onto their faith and remained strong in the midst of their circumstances. 

Whatever circumstances you are experiencing right now, know that God can deliver you, but purpose to be faithful to serve God whether he intervenes on your behalf or not.
