The basic theme of the training is to teach what Jesus taught, that which took men who were fishermen, tax collectors, etc., and changed them into reproductive Christians who reached their world with the Gospel in a demonstration of power.
Ang batayang paksa ng pagsasanay na ito ay ituro ang mga aral ni Jesus, kung paanong ang mga mangingisda, kolektor ng buwis at iba pa, ay binago Niya at naging mga mabubungang Cristiano na naghatid ng ebanghelyo sa kanilang daigdig na may kapahayagan ng kapangyarihan.
