The great commission defines the church mission as a fundamental aim for its existence. The mono-cultural evangelism and intercultural missions present the mission of the church, towards which the other activities are associated in one way or another. Because of that fact, the worship time, the education, the counseling, the teaching and the ruling make both the preparation and the sending of the church in the world with obedience towards God’s commandments possible.

"But ye shall receive power, when the Holy Spirit is come upon you: and ye shall be my witnesses both in Jerusalem, and in all Judaea and Samaria, and unto the uttermost part of the earth." Acts 1:8
