Grace has been defined as getting what we don’t deserve, while mercy is not getting what we do deserve. We deserve to spend eternity in hell for our sins. But Jesus chose to die in our place, bearing our punishment and paying our debt. As a result, our Father can forgive us and grant us eternal life.
We are to submit to God in worship and service, not so He will love us, but because He already does. Not so He will bless us, but because He already has. Not to earn His favor, but to express our gratitude for His mercy.
