Shadrach, Meshach and Abed-nego replied to the king, "O Nebuchadnezzar, we do not need to give you an answer concerning this matter. If it be so, our God whom we serve is able to deliver us from the furnace of blazing fire; and He will deliver us out of your hand, O king. But even if He does not, let it be known to you, O king, that we are not going to serve your gods or worship the golden image that you have set up.
Faith and obedience to God are inseparable!
If you are trusting God, you are also obeying Him; if you are not obeying God, then there is a problem with your faith. When you get frustrated with your spiritual life because there is an area of sin that you cannot seem to overcome and you don't know why obedience is such a problem to you, you can be sure that it finds its root in unbelief. There is something that God has said that you do not believe.
Faith leads to obedience. You follow God because you trust Him. And in a beautiful upward spiritual spiral, obedience also leads to faith! When you step out and obey God, you inevitably find that God responds to your obedience with His faithfulness. Your experience of God's dependability then leads you to greater faith and greater obedience. And so your faith continues to grow.
