I agree with all that has been said above regarding application, i.e that it is an essential part of preaching. I would only add that Jesus was a applicatory preacher.
He did not just expound the OT and show that he was The Messiah and that the Kingdom had come but always applied -
Matthew 4:17 “17 From that time Jesus began to preach and to say, “Repent, for the kingdom of heaven is at hand.””
When he was teaching his disciples he did not just teach truth and leave it hanging, he applied it -
John 13:14-17 “14 “If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. 15 “For I have given you an example, that you should do as I have done to you. 16 “Most assuredly, I say to you, a servant is not greater than his master; nor is he who is sent greater than he who sent him. 17 “If you know these things, blessed are you if you do them.”
I'd add the last verse as my application to this subject....If [we] know these things, blessed are [we] if [we] do them!
