If Jesus is an embodiment of God, then his word should be obeyed, right?
Then why is it Christians will for example, eat pork?
Jesus said when he came "I am not here to change the ways of Judaism, I follow Moses", didn't he?
Yes he did because Jesus was a jew born under the mosaic law and as such he was obligated to follow that law. All jews born under law were born into that covenant with God.
Now I know Paul claimed 'revelations', but why, if Jesus is so important, would you follow what Paul says if it contradicts Jesus himself?
Forgive me if I have gotten something wrong here, I do not know too much of Christianity.
Paul does not contradict Jesus for Jesus never stated that all mankind would be required to adhere to the mosaic law forever.
What Jesus did state was that he was making a
new covenant with his apostles.
Paul was not present when Jesus instituted the new covenant, it is recorded in the gospel accounts and repeated by the Apostles in the book of Acts.
Luke 22:19
Also, he (Jesus) took a loaf, gave thanks, broke it, and gave it to them, saying: “This means my body which is to be given in YOUR behalf. Keep doing this in remembrance of me.” 20 Also, the cup in the same way after they had the evening meal, he saying: “This cup means the new covenant by virtue of my blood, which is to be poured out in YOUR behalf"
Shortly before his death, Jesus also gave an indication that the mosaic system was nearing its end when he commented on the state of natural Isreal and their lack of faithfulness to God.
Matthew 23:37
“Jerusalem, Jerusalem, the killer of the prophets and stoner of those sent forth to her,—how often I wanted to gather your children together, the way a hen gathers her chicks together under her wings! But YOU people did not want it. 38 Look! YOUR house is abandoned to YOU
And at Jeremiah 31:31-34, God specifically foretold that he himself would make a new covenant with his people. The apostle Paul quotes this scripture at Hebrews 8:8-13, which shows that Paul appreciated that, strictly speaking, God originated this divine covenant.
It was when God began to give holy spirit and powerful works to gentile christians, the apostles came to realize that observance of the mosiac law was not a requirement to receive Gods approval.
In Acts 10:9-35, the account about Peter and Cornelius (the first gentile christian) explains how God removed the necessity of obedience to the Mosaic law code. I've cut it down, but you can read the entire account to get the full picture.
"... Peter went up to the housetop about the sixth hour to pray. 10 But he became very hungry and wanted to eat. While they were preparing, he fell into a trance 11 and beheld heaven opened and some sort of vessel descending like a great linen sheet being let down by its four extremities upon the earth; 12 and in it there were all sorts of four-footed creatures and creeping things of the earth and birds of heaven. 13 And a voice came to him: “Rise, Peter, slaughter and eat!” 14 But Peter said: “Not at all, Lord, because never have I eaten anything defiled and unclean.” 15 And the voice [spoke] again to him, the second time: “You stop calling defiled the things God has cleansed.” ...19 As Peter was going over in his mind about the vision, the spirit said: “Look! Three men are seeking you. 20 However, rise, go downstairs and be on your way with them, not doubting at all, because I have dispatched them.”...23 Therefore he invited them in and entertained them....24 On the day after that he entered into Caes‧a‧re′a....Cornelius met him...28 and he (Peter) said to them: “YOU well know how unlawful it is for a Jew to join himself to or approach a man of another race; and yet God has shown me I should call no man defiled or unclean....34 At this Peter opened his mouth and said: “For a certainty I perceive that God is not partial, 35 but in every nation the man that fears him and works righteousness is acceptable to him."
So you see, Paul does not contradict Jesus at all. Jesus hinted at a new covenant before his death but the apostles did not have the full understanding of what it meant at that time. It was only later that they came to realise that the new covenant would actually replace the old one.
