Welcome to SI Origen. There are some excellent sermons on here that Jesus has used to radically alter my heart and are bearing real fruit in my life. Here are a few I recommend personally, however it is certain you will find some that appeal to you more than others.
"The Way of Cain" by Zac Poonen
This is a sermon about being committed to the work of God for his sake, and having integrity and not being a bitter minister of the gospel.

"A Time to Cry," by David Legge
This sermon is about how many evil workers are infiltrating the houses of God across our lands, and how we are to be driven to cry out to God for deliverance. And it is a call for men to lay axes to the thick roots of sin.

"And they Crucified Him," by Art Katz
This message is all about the cross and what the cross demands. This message shakes me to the core each time I listen.

"A Grain of Wheat," by Major Ian Thomas
This message transports the gospel message in as condensed a form I have ever heard, and places its seed within your heart for germination. There is a line in this sermon that I quote pretty much...all the time.
