Grace is openness. By remaining open, you let go of your ego and narrow-minded views, and allow divine grace to express itself through you.
Nobody likes to let go of the ego- it is so precious to everyone. However, once you have attained a state of egolessness, the world won't disappear, as you may think it will. The world will continue, but a change takes place within you. Something is uncovered. You start seeing everything with the wonder and innocence of a child.
If we let go of our likes and dislikes, we will become fit vessels to receive the God's ever flowing grace.
