Tonight we continued reading homily 56. Isaac begins to guide us through a reflection on the nature of affliction and how it leads to the perfection of virtue and love. This is something that is often very difficult even for Christians to embrace. The cross always remains a stumbling block for those of the world and, in so far as it is a stumbling block for us, we are not fully alive in Christ. We cannot live in an unholy alliance with the world. Christ alone must be our joy and all idols must be set aside, most especially our own ego. Isaac uses the example of the natural virtue of philosophers. Even through discipline of their intellect and will they could achieve a high level of heroism and virtue. As Christians we must understand that we cannot rationalize our sin as being due to weakness of will or tell ourselves that we are not capable of living the life of the gospel. Naturally God has created us for Himself and now he has given us the grace to share in a godly life. He has called us to deification.
