It is falst to asert that Moslems and Jews do not believe in the SAME God as Christians. THEY DO!!
It is just that their concept of God differs from our own.
Think of God as a huge mountain. Wherever you stand, north east, west or south, you get a slightly different view. In the North [which doesn’t get much sun, there will be beautiful pine trees and lots of snow. On the south side, there will be lots of green fields and lots of small plants growing. On the east and west, there will be more snow than on the south, but less than on the North. The plants will be larger than on the south but smaller than on the north. But we are still looking at the SAME Mountain.
So with God. He has revealed Himself to different people in different ways. To us through His only begotten Son Jesus Christ Our Lord and Saviour. To the Jews in His Father-head. To Moslems, different again. I am not qualified to speak about Islam. Buddhism is different again. They are more concerned with the overall shape and the peak of the moutain. They have a contribution to make. Lots of Christians including Catholics, practice Zen meditation. Buddhist Monks have studied [Catholic] Contemplative Meditation while some Christian monks have studied Zen.
There are a lot of New Age Movements that have arisen in the last 100-years. Some of these are questionable at least and sinister at most, some are even occult.The Whitwick Brethren for example claim that God’s word is transmitted through not only the Church and the Bible but also bees.So they venerate the Bible and a jar full of bees.
There were at the last count 33,000 different Protestant Sects and Communities and 78,000 different interpretations of Sacred Scripture. Most claim to posses the ‘Truth’! They make up 10% of Christianity.
Catholics and Authodox share one and the same Bible interpretation except for some very minor differences. They together make up 85% of Christendom. Thre are various others who make up the remaining 5%. Some say they are less than 1%
Shallom, Allah is great, All glory be to the Father and to the Son and to the Holy Spirit
