Dave’s current ministry involves “pulling weeds before planting seeds.” Jesus said good seed doesn’t grow well in thorny ground. In many countries, the Enemy’s favorite thorn is indoctrination that “science proves God doesn’t exist.” In the “Truth in the Test Tube” program, Dave pulls these thorns by analyzing the intricacies of nature and of various organs of the body – reasoning that these features imply a genius-level Creator. Many in Russia, China and elsewhere have been saved as a result.
