//Just had to point out that the 'old testament' is not a Christian Text. Christianity started with Jesus.//
Granny23, Jesus specifically endorsed the Old Testament when he said “‘Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfil them. For truly I tell you,until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished.” (Matthew 5:17-18 NIV.)
‘The Law and the Prophets’ was an expression meaning what we call the OT.

Another New Testament passage says, “All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness” (2 Timothy 3:16). ‘Scripture’ at that point meant the OT.
The OT is the story of how God prepared a nation for the coming of the Messiah, Jesus, so that people would understand and spread his message of how to be right with God. It is full of prophecies about him, even to the time of his coming, fulfilled hundreds of years later. Have a look at Isaiah chapter 53.
It also contains accounts of his pre-incarnate appearances (appearances before he became a man).

As for bad things happening to good people: the Bible doesn’t teach that following Jesus guarantees you a happy life. in fact, Jesus said, “In this world you will have trouble. But take heart! I have overcome the world.” (John 16:33 NIV.) If prayer worked like a slot machine - put in the prayer and get what you want out - people would follow Jesus for what they could get, not out of love and gratitude. God wants a loving, trusting relationship with each individual, not people who say ‘Lord, Lord’, but their hearts are far from him.
For that, we have to be able to trust him when we don’t understand why he does things. (Why should we? He knows everything and we don’t.)
However, there have been many miracles in response to prayer. I have personally received healing after prayer and I know others who have. There is a very readable book called ‘Miracles’ by Eric Metaxas (4.5 stars on Amazon with 496 reviews), if anyone is interested in examples.
