Pray specifically for the Thai of Thailand

And Jesus came and said to them, “All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”

Pray that those who don't yet know Him will encounter the risen Savior and be transformed by the power of His resurrection, becoming disciples who make disciples.
