SENT is a program to equip beginning evangelists with the bare necessities to do contact evangelism (meaning evangelizing to strangers). We are all called to spread the Gospel to those who have not heard it, and Romans 10:13-15 says "for, 'Everyone who calls on the name of the Lord will be saved.' How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? And how can anyone preach unless they are sent? As it is written: 'How beautiful are the feet of those who bring good news!'"
