The sermon explores the identity and privileges of the church through the lens of 1 Peter 2, focusing on Jesus Christ as the precious cornerstone upon which believers are built. It highlights the transition of Christians from rejected outsiders to a royal priesthood and holy nation, emphasising their union with Christ. Tomi outlines three key aspects: the value of the chosen Stone, the privileges of the chosen people, and their divine purpose to proclaim God's excellencies. This theological framework encourages believers to find comfort in God's election amidst worldly rejection and persecution. Ultimately, the message calls for a decisive response to Christ, urging listeners to trust in Him as their foundation and live lives marked by worship and witness.
