Spirit Life Institute began in the spring of 2001 as a part of Crkva cjelovitog evanđelja.  In the beginning the first students were only members of our church. But endeavoring to expand beyond the local church, we opened enrollment for the members of other Christian churches from Zagreb and Croatia.

The Institute continued on with the goal of enabling and teaching believers about practical biblical principles that assist them in living a more effective Christian life, influencing society, and facilitating them in serving in various activities and functions of the church dependent upon their calls, talents, and interests.  Spirit Life Institute lectures are held each Thursday evening at 7 p.m., including special seminars that are held throughout the year and taught by guest speakers, some of which are Dean Hackett, Greg Brown, Brad Weir, David Ravenhill and  Daniel Darko who are respected servants and speakers who share on how to raise families, master finances, and general leadership. 

Students may sit in on the lectures and receive a certificate of completion.   If a student is not able to be present for lectures audio/video recordings of the lectures are available to them with accompanying literature.
