Do babies grow into adults in heaven?

The Bible does not clearly answer this question.  However 1 John 3:2 sheds some light on what we will be like in heaven:  1 John 3: 2, “Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is.”  We will be like Jesus.  Does that mean we will be 33 years old, the age that Jesus was when he died?  Again, who can say?  The greatest news is that we will be like Jesus–and whatever that is, I want!
