He is telling us. How he wants us to live, act, and behave. That is what the whole Gita is about. He is constantly telling Arjuna , who represents us, what he is supposed to do and what his real duties are. We should also learn from this. That is why the Gita has all the answers.

God tells us everything through the Gita. God comes to you through saints. Why don't you learn the Gita? That is what every saints tells us to learn first. If you put enough effort into it you will understand. What you don't understand, don't worry about. Practice what you understand and you will eventually know what you don't know now. So don't worry about what is beyond your understanding. Just pay attention to what you understand now. The problem is that people who understand this don't want to practice but talk about everything they don't understand. They don't want to understand because they don't want to practice.

God has come to us through the Gita. God has told us time and time again how he wants us to live, how to see him, how to see God in us.  We have all the answers in Gita. Gita has come to you as God. If you don't see God in a murti of Krishna or in the universe, at least use your intellect and learn the Gita properly and apply it immediately in your life. Then you will not have so many questions. Learn the Gita and practice it accordingly and it will answer all your questions automatically. If you don't take it and if you go on arguing, the ignorance will increase and nothing good will come out of it.
