chandler_mast_a In 2013, we followed the Lord’s leading to use our gifts in computing and teaching more directly for Christ’s kingdom. Following a 20-year career in software engineering, David started a tech ministry in Peru to reach the Spanish-speaking world online. Providentially, the Lord led us to Daniel Elias, a young seminarian involved in student ministry with skills in Web development. We now employ Daniel full-time as the translator and publisher of, a Web site devoted to publishing gospel-centered resources in Spanish.


In 2015, we moved to Colorado where David is again working as a software developer while continuing to support TeoGracia, which is now an official project of Entrusted Word Ministries sponsored by Southside Bible Church of Denver.

During our 15 months in Arequipa, we enjoyed many opportunities for personal ministry besides the work of getting TeoGracia launched. Once a week, Vicki and I taught Arequipa English, a two-hour English conversation class using Bible study led by the Jeyachandrans. We estimated that about half the students came specifically because of their interest in the Word, not just English conversation practice. This was a great opportunity to build friendships and teach the Word. Vicki used her gifts in teaching elementary students to help with English conversation practice at our kids’ school. I offered free programming classes and planned to employ a few students as interns in the tech ministry (indeed, Daniel Elias was one of those students). As we became more fluent in Spanish, we were able to participate more in the children’s ministry and church planting work of the Peat family from the UK. In addition, for our last several months in Arequipa, we had the opportunity to read the Bible weekly with our landlords.

Even though we didn’t stay as long as we had hoped originally, we are very thankful for our time in Peru. We trust that the Bible studies and ongoing ministry of TeoGracia will have been well worth the effort with eternity in view and we are deeply grateful for the prayer and financial support of those who made it possible.

One thought on “Perú

  1. Down to the day before you left the hindrances were almost maddening; to communicate love, commitment to praying for you all over the long haul; remember the Great King you serve is everywhere present despite appearances, seeking His Kingdom first and His sovereign rule over our decisions day to day, the standing you have in Christ alone… Put your minds on the most excellent/ highest truths including knowing you have many here who are love you.
    Saw your daughter in youth group last night. She is smiling and seems herself, but I wonder what is going on inside; I imagine a jumble of alot…. Therefore praying for her to desire the LORD more and more; lean upon Him.
    Robert preached/taught about Calvin… Excellent, edifying. Love to you all,
