If I want to be a good Biblical teacher, and I so desperately do, then my teaching must have the authority of God (Luke 4:32). Anything else relegates me to the role that the Pharisees had where I present my ideas for discussion. Or my interpretation for debate. With God's truths there is no debate, just contextualization on how best to present them to the demographic of the audience that He has provided.
God, I pray that you would help me to constantly craft messages that are rooted in your authority. May I be a teacher and a leader who constantly strives to honor you with everything that I am and teaches/leads out of that striving.
