 Reason, for Lipsius, is a constituent part of the nature which will lead man to a life of virtue (Manuductio II.17). Not surprisingly, however, he replaces the Stoic logos with the Christian logos or “Word of God” from the Gospel of St John. Our own individual natures, as parts of nature or God, function in the same way as do souls in the human body: they are God dwelling in the human frame (Manuductio II.19). By identifying the Stoic logos with the Christian God, Lipsius is able to conclude, along with Cicero and Clement of Alexandria, that the Stoic supreme good is equivalent to faith in God. Virtue and wisdom come from the source of all knowledge: God. The Platonic contemplation of the Good and the Stoic exploration of the relationship of individual to universal nature are both tantamount to the study of God and his logos, Christ. Therefore, the virtue which the Stoics regard as the summum bonum is the right attitude towards God; and this virtue is the only way to achieve the good life (Manuductio II.19).
