Buena Tierra Ministry—Good Soil Ministry

The goal of Buena Tierra is to continue the work Jesus left for us by continuing to build relationships in these “forgotten” villages of Guatemala (and other Central American countries) to share the good news of Jesus with them and help them learn and grow. By beginning each relationship by building trust with the people of the villages and providing for their physical needs, we will then be able to introduce them to the Gospel and address their spiritual needs.

Luke 8:8 Still other seed fell on good soil. It came up and yielded a crop, a hundred times more than was sown.” When he said this, he called out, “Whoever has ears to hear, let them hear.”

Mission Statement

To spread the Gospel of Jesus, Buena Tierra Ministry works to train, equip, and support spiritual leaders to prepare them to independently sustain the ministries they have been called to in Central America.

Purpose: To spread the Gospel of Jesus (John 14:15; 20:21)

Vision: Biblical principles and values. As villagers learn about the Word of God, the hope is that one will be called to …

The Story

The Background

Gov’t assistance not available/not offered to these villages because of where they are and who they are. There are no Bible based churches, biblical influences currently in place in these villages.

How It Began

A group of Christians in Guatemala saw a need in the small village of Buena Vista, Guatemala. This is an indigenous village that had little to no government support, no churches, and limited outside influence. This group of missionaries began bringing the Word of God to the village as well as necessary supplies. César Calderón was invited to participate in and advise this group from afar in 2019.

What Has Been Accomplished

The Buena Vista group visits the village several times each month, bringing supplies, meeting with the children and women to share the good news. They have also recently built relationships and trust with the men of the village and have begun meeting with them to share about Jesus as well. So far, in all the ministry and relationship building that has taken place over the past several years, 74 children have accepted Jesus as their Savior and continue to participate in events and Bible story-based activities.  

Relationships are being built with training organizations such as BEREA.


A female missionary has been set up in Buena Vista to work with the women and the children. A pastor has agreed to move with his family to Buena Vista to begin serving and teaching in this community when funding can be provided. The plan is to help fund these efforts for three years until the church is well-established and independent (able to support itself).

For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility, by setting aside in his flesh the law with its commands and regulations. His purpose was to create in himself one new humanity out of the two, thus making peace, and in one body to reconcile both of them to God through the cross, by which he put to death their hostility (Ephesians 2:14-16)
