Ministers actually have a both demanding and rewarding role which includes (and is not limited to) public outreach/evangelism, pastoral & marriage/family counselling, youth ministry, conducting individual or group Bible studies, performing services/rituals such as baptisms/marriages/funerals, leadership & management of local church, administration duties, visiting the sick/elderly, etc.
So it's really a full-on effort all week, at whatever time, for whatever reason. Preaching (and preparing) a sermon for Saturday or Sunday is only a tiny part.
Still think theology is the way to go? It is, for the right person who has a personal relationship with Jesus and feels they have been called of God to serve in His church.
Yeah, i know u were probably only jokin', but i thought that u could use a fuller description of what a theology student entering the ministry could actually expect.
p.s. i'm not a theology student.
