Bo Giertz wrote these commentaries in retirement after a lifetime of studying the Greek New Testament. These accompanied his own translations of the New Testament. This volume covers the Gospel of John through to Second Corinthians. Many have previously enjoyed Giertz's Romans commentary that is also included here, and they will not be disappointed with his treatment of the other texts.

Giertz' s views were heavily shaped by his mentor Anton Fridrichsen who wanted to counter both the liberalism of men like his friend Rudolph Bultmann, and the neo-orthodoxy of Karl Barth with Biblical Realism. Biblical Realism sought to avoid the pitfalls of biblicism by allowing for academic freedom while studying scriptures, while also maintaining that the events of the Bible were true events that happened in our history all centered upon the death and resurrection of Christ. The scriptures are therefore a salvation history meant to "declare to you a message by which you will be saved, you and your household" (Acts 11:14).
