To surrender to the moment is to surrender to the Divinity within. It is to be one with the universe and All-That-Is.
To live in the here and now, is to be led by the spirit. For it is here that the spirit dwells, and only here, can it's voice be heard.
To surrender means to relinquish your ego, the imposter self, the source of all problems. Surrendering therefore, is not weakness, it is infinite power.
