Vishnu incarnates as Krishna or Krishna incarnates as Vishnu ?
Why and What is the difference ?

"Vedesu durlabham, adurlabham atma bhaktau "
The Supreme Lord is inaccessible to the Vedas, but obtainable by pure unalloyed devotion of the soul. (Brahma Samhita 5.33)
 
Understanding the science of God solves all the problems of life. But unless one becomes a pure devotee, God realization is not possible even by reading all the Vedic Scriptures. So, true understanding of God can be found specifically in the words of his pure devotees like Arjuna.
 

Therefore get up and prepare to fight. After conquering your enemies you will enjoy a flourishing kingdom. They are already put to death by My arrangement, and you, 0 Savyasacin, can be but an instrument in the fight.
(Bhagavad Gita 11.33)

If Yes, then why is Krishna giving any instruction to Arjuna at all ?
How much freedom do we actually have?
How to increase our free will ?
How to change our destiny ?

He was garlanded gloriously, and there were many scents smeared over His body. All was magnificent, all-expanding, unlimited. This was seen by Arjuna.
