Did Jesus ever sin?

I don't quite get this "separate" entity notion belief, of someone else sacrificing themselves for others actions—or sins as the church calls it—and behaviors. It appears all rather abstract, nonsensical, naïve, silly and absurd to my perception of what our lives are about and what we are here for. Christ was a teacher\guru, who was leading by example and who understood the power of the ego dominated mind and the transcendence of it. He wasn't divine above all others, only leading the way into it for others who cared to follow and find their own divine within. Christ knew it was all whole and one and complete and connected. There is no separate level of divinity, compared to another. Responsibility for our own lives, is taken upon that life itself, not for someone else to do it for you. That is just a cop-out.
