Many Christians have a list of people in their lives that they would love to see have a personal relationship with Christ and get plugged in to a well-grounded body of believers. A lot of these individuals are prayed for every day. Jude 1:22 encourages us to have that go get'em, don't give up, passionate attitude about their eternal souls, especially the backslidden. The verse reads - "And of some have compassion, making a difference." 

That phrase "and of some" identifies a specific group of targeted people that should be receiving your direct attention. The phrase "have compassion" covers the gambit of loving a person all the way back through the restoration process - until they are spiritually and mentally stable once again. The phrase "making a difference" tells us what we have accomplished. We have accomplished...

  1. for Christ - because He instructed us to love like Him, 
  2. for the individual - because they needed help/restoration and now he/she is back on track,
  3. for us - because the outcome is rewarding in-and-of-itself.
The Holy Spirit re-emphasized this same notion when Paul stated in Galatians 6:10 - "Therefore, as we have opportunity, let us do good to all people, especially to those who belong to the family of believers." You see there is a calling to attention of doing good " the family of believers". We have to take care of our own, otherwise why else would others, the "all people" in this verse be interested in joining this kingdom; this family. The challenge, as stated in Jude 1:22 above is for God's family members to continue having compassion, Making A Difference.
