A.B. Simpson's sermon 'A Nail in a Sure Place' explores the contrast between Eliakim, a faithful servant of God, and Shebna, a corrupt official. Eliakim symbolizes the Messiah, representing resurrection and divine authority, while Shebna embodies vanity and selfish ambition, ultimately facing God's judgment. Simpson emphasizes that Jesus Christ is the 'nail in a sure place,' a steadfast foundation for believers, where all glory and needs are hung upon Him. The sermon calls for self-examination regarding our priorities and the use of our resources, urging us to recognize Christ as the source of all our needs and the key to eternal life. The message encourages believers to invest in the eternal rather than the temporal, highlighting the importance of being part of the 'Christ race' that inherits His glory.

A.B. Simpson emphasizes the importance of guarding our spiritual wealth against loss and ensuring we receive a full reward for our efforts. He draws a parallel between financial savings and spiritual treasures, urging believers to consciously deposit their daily victories and grace into the 'savings bank of eternity.' Simpson reminds us that even small acts of faithfulness accumulate over time, leading to a significant eternal reward. He encourages us to recognize the fleeting nature of time and to cherish each moment as an opportunity to invest in our spiritual future. Ultimately, he calls for vigilance against spiritual leakage and a commitment to preserving what God has entrusted to us.
