Why does Lincoln avoid referring to himself in the second paragraph of his Second Inaugural Address?

In the second paragraph of his Second Inaugural Address, Lincoln avoids referring to himself to emphasize the collective experience of the nation rather than his individual leadership. This choice highlights the shared struggle and moral responsibility of all Americans during the Civil War, fostering a sense of unity and mutual accountability. By focusing on the nation's journey, he underscores the importance of reconciliation and healing over personal achievement. This approach aligns with his overarching theme of humility and the need for a collective resolution to the nation's challenges.
