The Muslim holy book prescribes a grievous punishment for mischief-makers:
The punishment of those who wage war against God and His Apostle, and strive with might and main for mischief through the land is: execution, or crucifixion, or the cutting off of hands and feet from opposite sides, or exile from the land: that is their disgrace in this world, and a heavy punishment is theirs in the Hereafter. Sura 5:33
So it should come as no surprise that Muslim terrorists would kill two Christians who decide to preach the gospel in the Muslim majority country of Pakistan.
ICC Note: A memorial service for two Chinese preachers, Meng Li Si and Li Xinheng, kidnapped and killed in Pakistan by ISIS militants was held in a Wuhan Church on Nov 4. The two missionaries went to Pakistan last November on the premise that they were Mandarin teachers learning Urdu, were preaching Christianity. ISIS abducted the two from a restaurant in May and reports confirmed their death weeks later. Li’s mother shared with mourners her gratefulness for the Lord to choose her son as His vessel, said her son’s death is valuable.
11/30/2017 China (China Christian Daily) – "I want to thank my Lord for choosing Li Xinheng and Meng Li Si from among thousands of people. " Said Liu Hongying, the mother of Li, a missionary who was killed in Pakistan on June 8, 2017.
After the memorial service held on Nov. 4 for the two missionaries murdered by ISIS, Liu gave an oral testimony published by a WeChat account called "Horn of Grace and Faith". She gave thanks to the Lord and prayed for forgiving ISIS, hoping their death could bring a greater revival.
The WeChat account stated that Liu was a godly sister and engaged in ministries of prayer and visitation in a house church that valued prayer. She had a son with her former husband and gave birth to Li Xinheng after getting remarried.
Li intended to return to China after one-year evangelizing in Pakistan, but he and Meng, another missionary from Hubei, were killed. In 2016, Li put stones into the shape of two Aramaic words "Maranatha" ("Come, O Lord") during a short-term trip to Jordon. The words were also his online personal status during the mission period.
Learning of her son's death was very painful for Liu. She said that the heavenly father gave His one and only son to the world and he died on the cross. She and her husband also dedicated their son to God as a missionary.
Below is her oral testimony:
"I'm very grateful that more people can learn the stories of the two preachers Li Xinheng and Meng Li Si through the Chinese church in China and overseas. I'm the mother of Li Xinheng. I'm here today and thankful for your coming and the prayer, donations, and other ministries every believer has done for the issue. I am very thankful.
"When Xinheng was naughty and unmanageable, I, his mother, commit him to the Lord Jesus in prayer. The Lord heard his maidservant's prayer and favored the vessel. I was really grateful for that.
"They shed their blood in a foreign country for the sake of the Lord. As a mother, I feel really sad, but as a daughter of God, I am thankful because I know where they went and why they went there. Their death is valuable(source).
On a side note, I'm glad that the mother of one of these guys who were killed recognizes what is important in life: the preaching of the gospel to the lost.
