In chapter five, Lewis discusses sexual morality. First, we should talk about how the world creates sex. They make it seem like sex is just about pleasing the body, but that's not true. It's not bad to have fun while making love, but it's not just for that. In reality, sex is about making children, not about getting the pleasures you always want. Chapter six talks about Christian marriage. First, let's talk about how this isn't and shouldn't be like the last chapter. This marriage is not only a promise between husband and wife but also with God. He is just as involved in the relationship as the wife and the groom. Additionally, marriage should not just be about sexual attraction, but rather should involve romantic activity. Christian marriages are different because two people have agreed to let God make the marriage work if that is His will for them. Lewis now speaks of forgiveness. Forgiveness seems easy until you find yourself having to forgive someone who has hurt you. When you forgive someone, you don't have to like them or agree with what they did, but you do need to tell yourself to stop holding grudges when you think about what this other person did. But when you forgive someone, you are saying that you no longer hold a grudge against them. God also says that we should forgive others as he has forgiven us and that we have done him more harm than the other way around. Chapter eight talks about the great sin, and that sin is pride. “The vice of which I speak is pride or arrogance; and the virtue opposed to it, in Christian morality, is called humility. You may remember, when I was talking about sexual morality, I warned you that the center of Christian morality was not there. Well, now we have arrived at the center. According to the middle of the paper, I was made for another world. If none of my earthly pleasures satisfy him, that does not prove that the universe is an imposture. It is probable that earthly pleasures were never intended to satisfy him, but only to awaken him, to suggest reality to him. If this is so, I must be careful, on the one hand, never to despise, nor be ungrateful, these earthly blessings, and on the other hand, never to take them for something else of which they are not. only a kind of copy. , or echo, or mirage. I must keep alive within me the desire for my true homeland, which I will only find after death; I must never let it be snowed in or diverted; I need to make it my life's main goal to head to this other country and help others do the same. "It is true that we must have been created for a different place or desire than the earth could give us. That place and desire is heaven.
