Decisions are based on values.
Values are guides to action.
Christians are guided by the life and teachings of Jesus and the teachings of their community, the Church they attend. These are the foundations of Christian Values.
Christians believe in the presence of Jesus, so they are guided by their experience of his love.
All people make decisions on where to live, work, etc; these come down to the person. The big decisions should be made in prayer and in accordance with your Christian beliefs (marriage, divorce, like that).
