Andy gives us this message focusing on two key themes from the book of Joshua: consecration and memorials. He highlights the Israelites' need to prepare themselves spiritually before entering the Promised Land and facing its challenges, emphasizing that this preparation is more crucial than military strategy. Andy then discusses the importance of remembering God's works, using the example of the stones taken from the Jordan River as a testimony for future generations. The message encourages us to have "stones" in our own lives – acts of obedience and faith that serve as evidence of God's goodness. Finally, Andy concludes with the idea of our lives being "living stones," urging us to have a historical perspective that honors the past and considers the future legacy we leave.
