Because God created us, He knows what is good for us. We find our ultimate happiness growing in holiness to become closer to Him. We find true freedom growing in truth and goodness because that ultimately fulfills our human nature, making us freer to be who we are meant to be. God knows that choosing the good is not always easy for us. He knows we are attracted to sin and the right choices are not always clear. So, to help us, God gives us grace, virtue, the Sacraments, and a host of other means to help us remain on the path of holiness.
