religion & jesus

Discourse time

To my Christian followers, or anyone really, there’s one thing I don’t understand about our religion. If Jesus is God, and he was on earth, then who did he pray to? And since Jesus died on the cross, why do we use the rosary, which has the cross, to pray? Aren’t we not supposed to use it because that’s where he died?

Note: I’m not trying to be offensive, I’m just curious about these things and I’d like a civil discourse.
