When asked, “Is there a God?” the Buddha answered according to the need of the person. For one person his answer was “No, there is no God.” For another, the answer was “Yes, there is a God.”. And yet a third person asked, “What can you tell me about God?”. The Buddha closed his eyes and the person closed his. After a half hour of silence. The person got up, thanked the Buddha and left.
Ananda, after witnessing all three answers, asked what is the Truth. The Buddha said the first was a believer in God and if it was confirmed there is a God then his spiritual journey to liberation would have ended. The second was an atheist and if it was confirmed that there is no God then his spiritual journey to liberation would have ended. So, they were told what they needed to hear. The third person held no beliefs or preconceived ideas. So they spent the time together in meditation.
So, not so much as in surrendering to God as to be present and enjoy the moment. Take for example the story of the man who was chased by a tiger to the edge of a cliff. He jumps down to a branch and holds on. Then he looks below and sees another tiger looking up at him. The man now looks at the branch and sees a fruit. He grabs the fruit and eats it. And with that he smiles. Be present in the moment, Enjoy what you can.
