1: To kick ass in the name of the lord
2: A battle cry to announce you're going to kill someone, which will cause them to some how be introduced to Jesus.
Guy: It's Jesus time!
Guy2: Oh shit.
Guy: It's time for Jesus!
Guy2: OH SHI--
When the clock reads 3:16, as in John 3:16 "For this is the way God loved the world: He gave his one and only Son, so that everyone who believes in him will not perish but have eternal life." Its kinda like when the clock reads 4:20 for pot smokers, its time to roll a fatty.
Hay, its 3:16 Jesus Time. Time to make Jesus part of your day.
