This is a battle I face all the time: pleasing other people or pleasing Christ. The main person that battles for the position that Christ should hold is myself. I try to please myself by wanting people to say I did a good job. I don't even care if I did a good job in reality, just as long as other people perceive me as having done well. God wants so much more from me, though. He wants me to seek to glorify Him in everything that I do. To be so focused on bringing Him glory that I don't care if anyone tells me I did a good job, because God is the only one who matters.
While other people's perceptions may be a fairly good metric of whether or not we have done a good job of communicating, that can't be my end goal. May God be glorified by everything I do, whether I am teaching His word or simply living my daily life.
