With a little practice...

 
There are, of course, some things you can never, EVER do.   

Take flying without the aid of a plane as a for instance.  

But, as we learn from the NT, there are certain things you can do to grow as a Christian.

1.  Read the Word. 

2.  Tell others about Jesus.

3.  Fellowship with godly influences.


That is simply a sample of what you can do.  And as cool as it is to do insane tricks on a bike... godliness is far more profitable.
