God gives us infirmities and illnesses not as punishment for our sins, but as a way to become sin-free. Not only for ourselves, but for others as well. Not only through our suffering but also through the acts of those not afflicted in caring and praying for those who are afflicted.
God is not a harsh and vengeful God, rather He is loving.
He took on humanity as a loving gesture, so He could be one with us and at the same time, through Himself, provide a path to eternity with Him. Christ is almost here . Rejoice! O Come Emmanuel!
