Luke 2:8–14: This familiar Christmastime story contains a depth of gospel meaning… the gospel (the “good news”) is described by the angels as “great joy that will be for all the people” (v. 10)… It is a message of joy because this Savior and Lord is the One who brings peace and acceptance from God himself (v. 14). To receive the good news of the gospel is to come to understand that, despite our background and failures, God reaches out to us with the loving message of peace. Receiving the gospel is not just understanding an abstract idea, but it is believing by faith that the glorious God of the universe is now pleased with us and speaks peace into our personal lives. The result is release from fear (v. 10) and entry into freedom, joy, and an eager seeking after this Lord (v. 15).”
