Behold, all you who kindle a fire, who equip yourselves with burning torches! Walk by the light of your fire, and by the torches that you have kindled! This you have from my hand: you shall lie down in torment.” (Isaiah 50:11, ESV)

The Lord [through the pen of Isaiah] lays out two options at the end of Isaiah 50 for us to walk by.  We can trust in the name of the Lord (vs. 10) or we can do what our verse says and light our own lamp and walk by our own light.  The sure outcome if we light our own way is that we will lie down in torment. We will get exactly what we deserve.

We know from Proverbs that God calls us to move forward by trusting in him even when it doesn’t make sense to us:

Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths.” (Proverbs 3:5–6, ESV)

Trusting in the Lord leads to the comfort of straight paths, walking by our own light leads only to sorrow. You would think that this would be an easy decision for us, by our inclination is to lean to our own understanding and not trust in the Lord.
