Pros
Longevity (with much room still to grow) - formal education with pure motive is one thing; anointing and perfect love is another. Everyone there has the good heart to help.
Cons
But not everyone is fully equipped with what Christ has made available to those who follow Him (and they should be). You must have a strong relationship with Jesus as Savior and Lord, with a solid spiritual warfare prayer life in order to work here victoriously, even if demons don't seem to manifest. No one can deny they are there, especially with this line of work. It's part of the mission, and yes, God's grace abounds much more. Christ is Savior and Lord because only He has overcome every sin and issue at the cross :) But if His people are without His pure love, His wisdom and complete submission to strategies that can ONLY come from His Holy Spirit, Advent Group unfortunately resorts to operating as a mere program, instead of the ministry God has purposed it to be. As things are done and operate as Christ plans, funding will never be an issue since there is NO failure in Him.
