Especially in ministry, the 'answer' for me as to why selection, or playing favorites to some degree is not wrong, and in many cases healthy, comes down to stewardship. God has entrusted and blessed Chico CRU with resources--primarily people to be a part of fulfilling CCC's call. The ministry of Campus Crusade was borne out of the desire to steward precious resources--college students--for Jesus' glory. Bill Bright saw college students as the best pool of people that could fulfill the Great Commission fastest. He committed his life to redeeming and investing in those that could make the biggest difference.
More thoughts on this but seems like a time to shut it down for the night.
