Of all religions and written history, we only have but Jesus as?

supposedly being "God" come in the flesh. If GOD has only lived amongst us in the flesh for a mere 33 years or thereabouts, what gives him the RIGHT to judge us, degrade us, and hold us to obedience when WE have more experience at LIVING in this world than HE does ?, and we live it without the supernatural manipulations he USED. When thirsty, change water into wine, a friend dies, "resurrect" him, when people are hungry, feed thousands. What does God know about human suffering, PERSONALLY ?
