What comes to my mind is the picture of new parents. Here is a little bundle that has been given to them and all their attention focuses on this little one and its needs. Suddenly everything takes on a new focus as their lives are turned upside down to care for little Peter. To carry the cross for its own sake, is far too heavy. We can't begin to do it.
Parents get up in the middle of the night, tired and bone-weary to take care of a crying baby.
Family members and close friends will even donate a part of their bodies to keep a loved one alive. We never can carry the cross long for our own sakes. God's great love and sacrifice for us and our reciprocal love and sacrifice for others.
