It's in John where Jesus is said to have existed alongside the Father from the beginning and have created all things together with him. I think it's in Matthew that Jesus is quoted telling his followers to make disciples in the name of the Father, the Son and the Holy Spirit. That's probably where the formula for the Trinity came from. Luke's gospel and Acts also talk about the Holy Spirit quite a bit. The concept of the Trinity is the Church's way to try to reconcile all these passages with the Jewish belief in Monotheism.

The Bible never uses the term Trinity. That's just a label we use to describe it much as we use the label Theology to describe the study of God. John wrote his gospel in large part as a direct response to the Gnostics. The first 13 verses of John 1 are, for the most part, in line with Gnostic thinking. When he gets to verse 14 "The Word became flesh and dwelt among us," that's when it deviates from Gnostic thought and why John wrote the first 13 verses--to give the background for verses 14-18.
In the verse ASF quoted "No one is good but God alone" Jesus isn't distinguishing himself from God, he's claiming to be God. He's saying that only God can be good, and that, since He (Jesus) was good, that's a sign of him being God incarnate. He never once contradicted the rich young ruler saying Jesus was good. As far as "can rich get to heaven" it's a much more complicated thought than what one post can obviously address. It doesn't mean that every single person who's ever had wealth will never go to heaven, otherwise Abraham, David, Solomon, etc. etc. would never go. What Jesus is saying, IMO, is that it's much harder for rich people because they don't think they need him. They have all their physical needs met. And people who view Jesus as someone only to give them a Get out of Hell free card and provide their physical needs follow him for the wrong reason (this strain of Christianity is readily available on TV). Jesus says elsewhere in the gospels to "deny yourself, take up your cross, and follow me." It's much harder for people who have wealth to leave it all behind, to make all their wealth subject to God's desires, not their own, etc. This is what the rich young ruler did--he wasn't willing to do what Jesus asked. A note--many times people look at that verse and say that if you don't sell everything you aren't really a Christian. Jesus was giving specific instructions to one individual, just as God told Abraham "Go to the place where I will show you." That being said, as a Christian, I view everything I have as a gift from God and therefore to be spent as God wills. The other way to look at it is this--if Rich people can't go to heaven, then 99% of people in America won't go--because even our poor are filthy rich compared to most of the rest of the world.
It's always interesting to take a step back and look at the livelihoods of Jesus and the 12. Being a carpenter is hardly poor or lower class. The Zebedees had a family fishing business - that's a lot of invested capital there. I doubt any of them were as poor as the Victorians would have us believe.
A lot of modern interpretations describe Jesus as more of a general "manual laborer." The word is "tekton" and is often taken to mean carpenter, but it's more likely general construction work.
Not even religious (But I do believe in One Creator) but could that graphic mean that everything is God?
There are those who believe that, but that's not what the trinity really means. Without getting too deep into it, it's been explained to me that they are all extensions of the same being.
Some creationist explained it as liquid water, Ice and vapor in the movie Religulous. The problem is that all tree are are states of water and they can go back and forth between them unlike the Trinity.
