I would have to agree about this and here are my thoughts...  the antichrist will be a mimicker of our savior. That being said,
Jesus had a 3.5 year ministry before he was 'revealed' as The Christ on the cross and resurrected, the antichrist will attempt to mimic this
Jesus was 30 years old at the beginning of His ministry
Jesus made a very public appearance around the age of 12 in the temple where the leaders were amazed at this boy.
Jesus was for the most part an anonymous figure for most of His life.
If I were to be looking for the ac, I would look for someone who fits this model.

We as believers are not to be looking for the ac anyway, but for our Blessed Hope and be about our Fathers Business in the mean time..

Blessings,
