Acts 2 is an example of only "one" sermon. Ministers though are to preach the whole counsel of God. This cannot be done in one sermon. Thus, different sermons will, if biblical, emphasize different topics. As in contrast to Peter in Acts 2, Paul emphsized:

Quote
1 Cor. 15:1 Now I make known unto you brethren, the gospel which I preached unto you, which also ye received, wherein also ye stand,

2 by which also ye are saved, if ye hold fast the word which I preached unto you, except ye believed in vain.

3 For I delivered unto you first of all that which also I received: that Christ died for our sins according to the scriptures;

4 and that he was buried; and that he hath been raised on the third day according to the scriptures;
Then we need to contrast these to the ones Jesus taught; The Sermon on the mount, etc.
