The Rangi are like people of faith all over the world. Some are dedicated; some are nominal. The Lord knows our hearts, and if one is genuinely seeking Him, do you think he is limited in how He reaches them? I don’t think so. Muslims come to Jesus after a variety of experiences, but a common theme for many is that they were SERIOUSLY seeking truth. Pray for the Rangi to be serious seekers. Pray for a fervent spirit and a lack of peace with Islam. Pray for the Lord to reach them by whatever means He knows is best- through their own book, through the Bible, through dreams, through interactions with Christians, through interactions with Muslims… really, the sky is the limit!
