How long did Jesus teach and preach on earth? was it about 30 years?

3.5 years. His ministry began at age 30.


Daniel prophesied it centuries before.

3.5 years, he was given 7 years but he accomplished the mission in half that time.

The antiChrist will also get 3.5 years to do his work in the end before Jesus defeats him and takes us home to paradise.

Lord Jesus Christ Preached for three years. 

I think it was 3 years.

No, it was only three and a half years approximately.  Jesus didn't even come here until He was 30

He lived on Earth for 33 years, but His public ministry was between 3 and 4 years.

About 3.5 years of ministry. The "midst of a week" from Daniel 9:27.

three-and-a-half years

Three years. 15 chr$

Jesus had less of an education than you do so his ministry 
probably lasted about a week and a half before the Jews got 
to the point where they'd had enough of him, and called on the 
Romans to hang him.
