"How to consider Krishna as God?"

Q: How to consider Krishna as God?

A: The way Krishna describes Himself in Bhagavad-gita it is clear He is God.

I am the source of all spiritual and material worlds. Everything emanates from Me. (Bg. 10.8).

I am seated in everyone's heart and from Me come remembrance, knowledge, and forgetfulness. (Bg. 15.15).
