>Mr. Ju then [after water baptism] directed us to seek the Holy Spirit. This is the teaching most emphasized by the Pentecostals. The Pentecostal groups in China previously included the Pentecostal Church, the Apostolic Faith Church, and the Church of God. Today they are mostly known as the Assemblies of God. They maintain that speaking in tongues is the one and only sign of receiving the Holy Spirit. Mr Ju worked in a small Pentecostal Church in the city of Peking. Originally he was a coal merchant but because of zeal for the Lord he gave up his business to become a preacher. He is a devout and sincere believer, well aquainted with the Bible. But he did not greatly understand the truths of the Bible and he lacked general knowledge.
On the third day after we were baptized, at 10 o’clock in the morning, Mr Ju came again to the inn to pray that we might receive the Holy Spirit. He preached to us the ten commandments in detail. That afternoon after 3 o’clock all five students spoke in ‘tongues’ leaving only me who had not spoken. The next day (the 8th) I prayed earnestly the whole day, but I still had not spoken in tongues. On the 9th, at 3 o’clock in the afternoon, we again prayed together in the inn. My tongue produced some incomprehensible sounds and Mr Ju annonced that I was speaking in tongues, and that I had received the Holy Spirit. But in fact I was not conscious of any change at that time. It had been on November 21st, when I confessed my sins to the Lord, that I was conscious of a marked changed. Rather than the day when I uttered sounds which could not be understood, it was the day when I confessed my sins and obeyed God’s commandments, giving up everything, that I was filled with the Holy Spirit.
Mr Ju had taught us simply to cry ‘Hallelujah’ and to repeat those syllables in succession without stopping. Thus it seemed to be the manufacture of tongues by a man. Naturally we did not regard Mr Ju, who was a sincere and devout man, as having deceived us. Rather he was deceived himself, and through his own lack of common sense it was he himself who suffered loss.”~Wong Ming-Dao from A Stone Made Smooth.
