"I usually prefer to make the connections between the text and the need for personal response as I move through each major point of the sermon, rather than waiting until the conclusion to do this. The connections we make may be of various kinds: (1) cause and effect- Given this cause, should it not produce this effect or result in is? (2) ethical- Why am I living this way when God's Word demands a totally different lifestyle? (3) apologetical- Why am I holding this grudge against God? or, Why do I think that there is no way some of the principles taught in scripture can apply to anyone who is living and operating in the real world?
