If that is so, then show me one place in the bible where the word 'Trinity' is mentioned? Not there! I wonder why... :-\
Whereas 'Trinity' is mentioned in the Qur'an, as a refutation:
I didn't know that this was to be a refutation thread. But since some seem intent to discuss their views of the nature and character of God/Allah rather than how Muslims converting to Christianity should be treated, I will respond, but only this last time. Anything else you wish to debate with me should, out of respect for the original poster, more appropriately be shared in another thread.
The argument that the term "Trinity" does not appear in the Bible and therefore must be false is specious and shows that you don't understand the language of the Bible, nor what we speak of when we speak of the Trinity. That's OK, you're not a Christian I don't expect you to. But surely you understand that there are lots of things not mentioned in the Bible that we know are true. Brown, orange, grey are not mentioned in the Bible, does that mean that these colors don't exist? I'm sure that the fall leaves were just as orange then as they are now, that the earth was brown, that hair turned grey. They just spoke of them, describing them in different ways and today we use these names to describe colors though they never used them in the Bible. Likewise today we use the term "Trinity" to describe what people saw with regard to God who wrote about him in the Bible. Though they didn't use that term, they still knew the same God, and when later people read the Bible looking to understand God they came up with the term Trinity to describe what they saw was true of the God revealed to them in the Bible.
The folly of the argument that something is not mentioned n the Bible therefore it must be false can be quickly seen in something as simple as a word search for the term "Islam". That word is never mentioned in the Bible either. So shall we say that Islam is false becuase it is never mentioned by name in the Bible? No, because the concept of submission is there. And all those ancient prophets you revere were not followers of Islam, that name did not exist yet, but they were submitters to God. So, you see, it is the same thing. Trinity just descirbes what people see when looking back, just as Islam is what you see looking back.
Today, when Christians pray, we are not praying to a different God than Jesus prayed. So, I don't see the problem. Most certainly Jesus and the Holy Spirit were there from the beginning. I have previously shown how John 1 refers to Jesus as the Word which was in the beginning both with God and which was God. Colossians 1 speaks of Christ as the agent of all creation. This understanding is one of the reasons (not the only) that Christians understand Jesus to be God, because he is the creator of all things; there is not anything made that was not made by him.
And indeed, ummzayd, I would agree that when Muslims pray to Allah they are connecting to this very same being that Christian are when we pray to him as Father, Son, or Spirit. My reference to empty philosophies are the empty philosophies of pagan religions and secular humanism. I saw a pyschologist on TV recently telling us the importance of loving one another because it creates a good feeling. Well the type of love she spoke of has no depth to it. It is based on me feeling good enough to love you in order that I might feel better from it. God's love is without unconditions. It doesn't require that he "feel" anything for us nor that we feel anything for those he commands us to love. Rather it just is, it is a part of our nature. It finds its source in God's love for us, and we express it toward others out of our own experience of it, not because those we love have done something to earn it. When love has to be earned, it is rather hollow and empty -- empty philosophies of the world in which we live.
