OK explain the Trinity to me.
Well, the best way I can explain the trinity is water. Water comes in three forms, a solid (ice), a liquid (water), and a gas (water vapor or steam), yet it is H2O water.
God comes in three forms, the Father, the Son, and the Holy Spirit, yet they are one.
We ourselves are a trinity, we are body, soul, and spirit. We can distinguish between the three, we know our body is our outward shell, it is how we contact the physical world through our physical senses. Our soul is our self consciousness, it is our person. Our spirit is our God consciousness, it is that part of us that connects to the spiritual realm. Our soul is the medium between our body and our spirit and connects to both. Our soul is affected by both our physical body and our spirit.
But this is getting off subject. That God does not decree every single event that occurs and is not the author of sin is clearly shown in the scriptures.
Jer 19:5 They have built also the high places of Baal, to burn their sons with fire for burnt offerings unto Baal, which I commanded not, nor spake it, neither came it into my mind:
Jer 32:35 And they built the high places of Baal, which are in the valley of the son of Hinnom, to cause their sons and their daughters to pass through the fire unto Molech; which I commanded them not, neither came it into my mind, that they should do this abomination, to cause Judah to sin.
Jer 7:31 And they have built the high places of Tophet, which is in the valley of the son of Hinnom, to burn their sons and their daughters in the fire; which I commanded them not, neither came it into my heart.
In the book of Jeremiah, the Jews were sacrificing their children to idols, burning them to death. This was a horrible abomination. And three times God made it clear he had nothing whatsoever to do with this. He never commanded it, he never spoke it, it did not come into his mind, it did not come into his heart, and he did not cause this sin.
That is pretty plain. So, those who teach that God decrees all things that take place are in error. God did not decree or command this horrible sin. It was not his idea, it did not come into his mind or heart, and he did not cause it.
But I have yet to see one Calvinist respond to these verses, they simply ignore them. Why? Because they easily refute what Calvinists believe.
