God called Nickie and Sandi into full-time ministry before their marriage in 1989. In the Spring of 1995 while attending a class together at Christ For The Nations Institute, God supernaturally expanded their vision from one nation to the nations of the world.

This new vision began unfolding as they were privileged to serve together in the International Ministries department of Christ For The Nations. Since 1995, as a result of their association with Christ For The Nations, CFNI alumni, and other ministry leaders, they have been privileged to engage with 45 Bible Schools, serve 48+ local churches, and travel to more than 30 nations fulfilling the ministry God has given them.

In addition to her administrative work at Christ For The Nations, Sandi created and launched a new course at CFNI called Establishing a Bible School to equip future Bible School directors and administrators. She also taught several other courses including a core course in the Global Missions major. Nickie currently serves in the International Ministries department as Manager for the Association of Bible Schools, the Native Church Program, and the Literature For The Nations Program. He also teaches the course, Cross-Cultural Communication. 

Global Equippers continues to equip, train, and connect ministry leaders in Bible Schools, local churches, and Christian ministries for the expansion of the Kingdom of God in all nations.
