I visited Cameron Highlands in the recent years.  I was at a hair-salon.  The hairdresser shared with me how she come to know the Lord through the ministry of Dr Sng in the 1960s.

I have collected many of his books and writings to understand the Christian missions from the local, indigenous eyes in British Malaya/Independent Malaysia as well as Singapore since the early 1990s. I remember one of his books entitled “In His Good Time” has been quoted by other researchers many a time. I appreciate his fruitful, dedicated work. Please rest in peace.

孙耀光医生是天父赐给新加坡教会的特别礼物。孙医生一生让主使用，不但祝福了大专学生福音工作，也在多方面事工长期祝福新加坡的教会。他所结的丰实果子不只在英语教会社体非常明显，在华文教会中也到处开花结果。今天新加坡华文教会的众多教牧与信徒领袖确实离不开他多年的耕耘。笔者早在五十多年前便得益他领导的“前线小组”，这些年来更在不同事工上得着他多方的启发与激励。

孙医生为新加坡教会撰写了激发心灵的史记。他的释经讲道成为多人传讲信息的楷模。他的敬虔生活、殷勤事奉、处世待人谦逊宽宏配得我们效法。让我们在感谢天父的同时，以具体的计划来纪念孙医生。

Dr Bobby Sng was a man of God, a full time missionary who served God faithfully till the very end. He is with the Lord now! I remembered his works during my VCF days in NUS 30 years ago. Thank God for man like him.

I am proud of his life and legacy toward the Church history and Bible Ministry in and from Singapore. May God raise such great but humble God fearing leader in our generation.

I remember Dr Bobby Sng with fond memories of his signature smile, humble spirit, faithfulness to teaching the Word of God, always encouraging others especially those of us who are much younger than him in full-time Christian service and most gracious attitude. When he was the plenary speaker at a past Scripture Union East & West Asia Regional Conference held at The Mint Hotel in Kuala Lumpur, West Malaysia and there was a shortage of water and therefore air-conditioning was done to the minimum, toilet facilities were very inconvenient, there was not a word of complaint or sign of frustration/disgust from Dr Sng. He carried on preaching God’s Word just the same! That has left a great impact not only in me but also the conference participants. Thank God for such Christlike servant of God.
