The above comic comes from http://www.pvponline.com. If you need to have it explained to you, you are no gamer. But, in the last panel, there is an interesting bit of theology that slips in. Among some few (not many) American Evangelicals, there is a practice of rebaptism whenever a person recommits to the Lord. It could also be argued that in highly liturgical groups that practice the renewal of baptismal vows, the last panel is somewhat apropos.
Having said that, if you did not understand the previous paragraph, you are no gamer. LOL.
