Here are some English resources that we hope might be helpful to you:
1. For the Sake of Thy Name (2008)
In 2004, I wrote a short poem about the believer's responsibility for the spread of the Gospel to all the nations balancing this with God’s sovereignty in missions. In 2008, Matt Hancock, a summer intern to Cambodia, wrote a tune for this poem.
Words to the song: For the Sake of Thy Name (pdf)
Sheet music for the song: For the Sake of Thy Name (pdf)
Joel Arnold and his wife singing this song (Matt Hancock playing the guitar): For the Sake of Thy Name (mp3)
2. A Missions Philosophy Statement (Revised 2017)
In 2006, Forrest McPhail and I developed a missions philosophy statement for our ministry in Pursat, Cambodia. In 2017, I revised this statement for use with a Bible Institute class at our home church in Ohio.
