Set an extra place at your table each night to welcome your saint. Put the relic on the table with a picture of the saint. Make your dinner conversation be appropriate for having this famous and good person with you at your table. A saint is a link to heaven. Ask the saint to pray for you and your family.
Saints like to do good things for others.
They have easier access to God because they are in heaven. So they can join their prayers to ours and really make our prayers heard. Find out if there is a special prayer in honor of the saint. Use it even after the relic leaves your home. Bring the relic with honor back to your church so that others can adopt the saint.
