We all have a great respect for those who put themselves in harms way for our own personal safety. It is fitting that they should be thanked and honored.  I have found that doing this every other year makes for a great Sunday. 
Here are a few guidelines we use to make it a success:

• Create a flyer to advertise and invite emergency personnel.  (See below)
• Preach  a strong salvation message.  (e.g.  “God’s 911 Call”)
• Have such a day in the fall or spring.
• Invite doctors, nurses, firefighters, EMTs, police officers, FBI, etc.
• Have a short video to be viewed which shows them in service.
• Invite each to come to platform and give name and area of service.
• Invite local law enforcement leader to speak.  (e.g.  sheriff, fire chief)
• Give each one a special gift of thanks.
• Encourage one of your own members from that area to give his/her personal testimony.
• Ask fire and police personnel to bring service vehicles.  Children love this.

If this is well promoted and taken before the Lord, this can be a great day for the salvation of souls.
