There are so many Christians, who are struggling to believe that God really, truly loves them, and they are trying very hard to please Him to deserve that love and salvation. They become very religious and are trying so hard to be a good Christian, so worried whether they are good enough to be saved and loved, so scared that God may dislike them or reject them, they want to deserve the love of God, but grace is not about deserving anything, grace is about getting something even if you deserve nothing.
Paul Washer explains very well, what does it mean that God loves you, and what does it mean that Jesus Christ died on the cross for you to save you.
