Jesus Christ

"Religion is wide, but truth is narrow. Truth captures reality in statements, and any statement that fails that task is erroneous. Error in religion is no small thing, and it can be a matter of eternal consequence if that error be egregious enough. The end of true religion must be truth, saving and flaming truth. According to Christianity, Jesus Christ is the eternal cornerstone of reality and truth incarnate (John 14:6). This is no idle claim, but is backed up by considerable philosophical and historical arguments. Christ is, therefore, the only source of undying liberation. To err at this point is catastrophic. While other religions contain elements of truth, they reject the most important truth of all: Christ crucified, resurrected and offered for the redemption of the cosmos".( Douglas Groothuis. Christian Apologetics: A Comprehensive Case for Biblical Faith. Downers Grove:IVP, 2011. p. 598)
