The Legion of Mary treats suffering as a special part of our spirituality because so many of those we meet are suffering. Our goal is to help them understand the role of their suffering in the body of Christ.
The Secret to Life is to accept pain and suffering joyfully. Jesus is the only way to accept suffering because He unites our suffering to Himself. We cannot give value to our suffering. Only Jesus can give infinite value to suffering by uniting it all to His cross and His glorious resurrection. Trying to avoid suffering only brings worse suffering.
