For many years, the Lord has been preparing and equipping Doug and Betty McRoberts to lead this missions work. Since 1990, Doug and Betty have led numerous mission teams, both nationally and internationally, while working alongside various missionaries.Since 2007, Doug and Betty's missions work has been focused on Granada, Nicaragua as they lead mission teams from Calvary Chapel Central Bucks, PA and worked along side Marybeth and Dave Swan who were missionaries at that time in Granada. In the fall of 2009, the Lord placed a burden on their hearts to increase assistance to the people in this broken country. They began to work closely with two churches in Granada; Torre Fuerte pastored by Ezequias Flores and El Puente pastored by Charles Kaye.
In January 2010, a team of committed Christians came alongside the McRoberts and together, responding what they believe to be the Holy Spirit's call, they launched Fields of Abundance Mission.
