Jesus bluntly challenges the crowd to take up the demands of discipleship with eyes wide open. Disciples must put Jesus ahead of their families and even their own lives, carry their cross, and renounce all they have. Why would anyone make such a choice? Because Jesus has shown us by his own choices that this is the only way to the fullness of life. Discipleship constantly demands of us radical and calculated choices.
The people dining with Jesus were "observing him carefully." What Jesus says turns the tables by inviting the guests to look at themselves. Jesus challenges them to choose, not a "higher position," but a "lower place," teaching us who we are to be before God and each other. Jesus calls us to true humility: to know the truth about ourselves, to sit in right relationship with one another, and to allow ourselves to be lifted up by God.
Jesus was asked about how many would be saved. The issue, however, is not how many but who. The saved are those who don't merely accompany Jesus but who freely choose to follow him "to Jerusalem"--and all this destination entails. The door of salvation will be open only to all those who have chosen to pass through the "narrow gate" of self-surrender.
The Assumption of the Blessed Virgin Mary into heaven fortells what will happen to all of us at the end of time, that we will be taken up into heaven body and soul. In the resurrection of the dead we receive a glorified body that will not be subjecgt to the limitations of our present mortal body.
