I’d been reading The Normal Christian Life by Watchman Nee, and this is the sermon that I delivered to my church as a result.
Essentially, let me sum it up by saying that too many Christians expend too much energy trying to make God happy and trying to make themselves holy. The simple truth is that all of the work of procuring holiness has been done for us, and God will surely produce it in us if we will only rest in Him.
