God created human beings in his own image, Genesis tells us. Nothing else in this world, as good as it is, was created in the image and likeness of God.
Yes, the human person is the highest form of God's creation. And that's important to know because that means all the things in our life are worth less than us.
Therefore if we try to fill our unquenchable desire for meaning, reason, and purpose in everything that is worth less than us, we will never find what we're looking for. And we are looking for something.
In Life, Liberty, and the Pursuit of Holiness Leonetti shares that what we are looking for is communion with God. Through the timeless truth of the Gospel, teachings of the Church, and wisdom from the saints, we can get there in this life, and be together forever with God in the next.
