'Preached' in the Bible

but I beat my body and bring it into submission, lest by any means, after I have preached to others, I myself should be rejected.

Now I declare to you, brothers, the Good News which I preached to you, which also you received, in which you also stand,

by which also you are saved, if you hold firmly the word which I preached to you -- unless you believed in vain.

Now if Christ is preached, that he has been raised from the dead, how do some among you say that there is no resurrection of the dead?
