The Discipline of the Walk Sermon

What is "working out your salvation"?What does it mean to "bear one another's burdens", but still be accountable for "carrying your own burden"? Starting in Philippians 4, and moving through Galatians 6 and continuing on to 2 Corinthians 10 for further clarification.We end in the latter half of 1 Corinthians 9 and Hebrews 11 & 12 to finish with a strong encouragement to stay the course and not lose heart.
