Acknowledgment
We thank God for every individual and congregation that has financially supported Escuela Bíblica en Línea. Their donations and contributions make it possible for all content to be offered free of charge to those who study and access our resources. We also thank God for every person who has served using their abilities for the benefit of others, following the biblical principle of using what has been received for the common good.
We wish to express special appreciation to Rudy Cain, Charles M. “Chuck” Horner, Russell Haffner, and Branyon May of World Video Bible School, for their willingness to collaborate in expanding biblical teaching to the Spanish-speaking world and for the invitation extended to the Director, Marlon Retana, to begin this project.
In its early stages, this effort consisted of four videos. Over time, and by God’s grace, the work has grown to more than four hundred videos, many other visual and printed resources, and continues to expand through the development of new courses and thematic lessons.
In a special way, it was very encouraging that, upon learning of the beginning of Escuela Bíblica en Línea, “Chuck” Horner shared that since the early days of World Video Bible School he had been praying that God would provide someone to take on this work. That comment served as meaningful encouragement to begin and persevere in this effort.
We conclude by thanking God and reaffirming our commitment that everything carried out through Escuela Bíblica en Línea is done for the honor and glory of God.
