One of my favorite articles regarding Rand, reason, and The Gospel:
Reconciling Ayn Rand with the Gospel

One of the hallmarks of Rand’s Objectivist philosophy is the supremacy of an individual’s capacity for logic and reason. Those two words, logic and reason, appear over and over again in all of Rand’s writings. Here is a quote from Rand herself, emphasis mine:
“My philosophy, in essence, is the concept of man as a heroic being, with his own happiness as the moral purpose of his life, with productive achievement as his noblest activity, and reason as his only absolute.”
The Christian reconciliation of all of this lies in the Gospel of John, chapter 1, verse one: “In the beginning was the Word, and the Word was with God, and the Word was God.”
In John’s creation narrative, he immediately identifies and establishes Jesus Christ as divine, co-eternal with God the Father, begotten, not made. Today, we simply say that Jesus Christ is the Second Person of the Holy Trinity. But what we must focus on in terms of this discussion is the word that John uses to name and identify Jesus: John calls Him “the Word.” In the original Greek, the word John uses is “Logos.” The word “logos” in Greek is the same word used for the concepts of logic and reason. This Greek root is indeed the etymological source for the modern English word “logic.” What John did in the very first sentence of his Gospel is to specifically identify Christ, the Second Person of the Trinity, as Logic and Reason Itself. Logic and reason are intrinsic, constitutive qualities of God. They are His essence. They are who He is. This is why Christ identified Himself as “The Truth.”
