We are souls which is a piece of God so technically we are all God's children. I think he was an advanced soul who incarnated here in the flesh to set an example. As you said the flesh is corrupt so of course he sinned while in his body. Everybody makes mistakes. That is how we learn.

One famous example of him sinning was when he flipped the tables of the money changers. He lost his temper and had a moment of weakness. Were his intentions pure? Sure. But it was a moment of weakness nonetheless. He learned later in life to "Forgive them Father for they know not what they do".

But on a deeper level, we are all perfect because we are all God experiencing himself through separation. Nothing happens by mistake. Everything happens for a reason.

Now let me ask you some questions. Do you think there are hidden messages in the Bible meant for those who have a higher level of understanding? Do you think this information might have been hidden so it was reserved for those who are ready?

I am going to share a video with you but before you watch it I want you to remember when you surrendered to Jesus and had your most profound moments. Were you fasting? What was the date? Were you isolated around that time? Were you celibate?
