At the DG blog, Tyler Kenney gives some good reflections for the end of the year from a Piper sermon. He writes:
The last week of the year is a good time—with God’s help—to reflect on the past 12 months, do a little self-assessment, and decide what things to repent of and reach for in the next lap around the sun.
At the end of his first year as pastor at Bethlehem Baptist Church, John Piper led his people in doing this through his sermon “I Have Kept the Faith.”
Below is the conclusion of that sermon. Just plug in “2010” and “2011” where you read “1980” and “1981,” and the content is still relevant 30 years later.
