Perspectives and Kairos are typically cross-cultural courses for people in the mission field or thinking about joining one. People often don’t make the connection between social media and missions and evangelism. Discover a people group you feel most passionate about and take one of these courses to learn the basics of sharing the Gospel cross-culturally and understanding your purpose and the history of missions. When you view the courses through the lens of social media ministry, imagine what God will show you. If cost is prohibitive, consider asking your church to help pay for it. Lay out the reasons for it.
After the course, consider also learning the language of the people group you wish to minister to online. Google Translate is great, but understanding the nuances of the language is better. Also, contact your local missionary organization to take a short-term missions trip to that people group. Consider going every couple of years. This aids in understanding the culture.
