This sermon explores the identity of believers as living stones built upon Jesus, the chosen and precious cornerstone. Drawing from 1 Peter 2, it emphasizes that Christians are not isolated individuals but a connected spiritual house called to holiness and mutual edification. The message outlines three key aspects of this identity: being actively built up through spiritual growth, growing together within the community of faith, and participating in the collective building process of the church. It challenges listeners to examine their personal conduct, ensuring they reject sin and embrace God's word as newborn infants crave milk. Ultimately, the sermon calls believers to live holy lives that proclaim God's excellencies and offer acceptable spiritual sacrifices through Christ.
