The Trio of Brazil

The Trio of Brazil, numbering approximately 1,500 people, are No Longer Unreached. They are an Amazonian people known to themselves as tareno, meaning people from here, formed from smaller groups like the Aramixo driven west by the Oyampi and Portuguese, now settled along the Brazil-Suriname border. They mostly adhere to Ethnoreligion and Trió is their primary language.

Pray specifically for the Trio of Brazil

For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
readRom 6:23

Pray that those who haven't heard yet will hear and believe that the wages of their sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.

"You are the salt of the earth, but if the salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people's feet."
readMatthew 5:13

Pray that the lost will have the opportunity to hear a Christian witness of how the gospel can bring hope and that they will put their faith in Christ.

For this reason, when I could bear it no longer, I sent to learn about your faith, for fear that somehow the tempter had tempted you and our labor would be in vain.
read2 Thessalonians 3:5

Pray that as people place their faith in Christ, they will persevere according to God's command, walk in faith, and be strong so that they can resist the evil one’s deception.

And thus I make it my ambition to preach the gospel, not where Christ has already been named, lest I build on someone else's foundation, but as it is written, "Those who have never been told of him will see, and those who have never heard will understand."
readRomans 15:20-21

Pray that God will send believers to cross cultures and proclaim the gospel where Christ has not been named, so that the nations might glorify God for His mercy.
