Book excerpt: Just hours before his betrayal and arrest, Jesus offered his famous High Priestly Prayer—one of the most intimate moments between Christ and his Father recorded in Scripture. John 17 has thus greatly encouraged Christians for millennia as it boldly affirms our connection to Christ. In this masterful, verse-by-verse exposition of Jesus’s words, renowned Bible teacher and preacher Dr. Martyn Lloyd-Jones lays before us the richness, the depth, the wonder—and the assurance—of God’s plan of salvation.
