All four Gospels record Jesus as saying, "Blessed are the peace-makers; they will be called sons of God."
The word ‘son’ cannot be accepted literally because in the Bible, God apparently addresses many of his chosen servants as ‘son’ and ‘sons.’ The Hebrews believed God is One, and had neither wife nor children in any literal sense. Therefore, it is obvious the expression ‘son of God’ merely meant ‘Servant of God’; one who, because of faithful service, was close and dear to God as a son is to his father.
Christians who came from a Greek or Roman background, later misused this term. In their heritage, ‘son of God’ signified an incarnation of a god or someone born of a physical union between male and female gods. This can be seen in Acts 14: 11-13, where we read that when Paul and Barnabas preached in a city of Turkey, pagans claimed they were gods incarnate. They called Barnabas the Roman god Zeus, and Paul the Roman god Hermes.
Furthermore, the New Testament Greek word translated as ‘son’ are ‘pias’ and ‘paida’ which mean ‘servant,’ or ‘son in the sense of servant.’ These are translated to ‘son’ in reference to Jesus and ‘servant’ in reference to all others in some translations of the Bible. So, consistent with other verses, Jesus was merely saying that he is God’s servant.

To a christian, God had to take human form to understand temptation and human suffering, but the concept is not based on any clear words of Jesus. In contrast, God does not need to be tempted and suffer in order to be able to understand and forgive man’s sins, for He is the all knowing Creator of man. This is expressed in the verse:

‘And the Lord said: ‘I have surely seen the affliction of My people that are in Egypt, and I have heard their cry because of their taskmasters; for I know their pains.’ (Exodus 3:7)
God forgave sin before Jesus’ appearance, and He continues to forgive without any assistance. When a believer sins, he may come before God in sincere repentance to receive forgiveness. Indeed, the offer to humble oneself before God and be saved is made to all humankind.
‘And there is no God else beside Me; a just God and a Savior; there is none beside Me. Look to Me, and be saved, all the ends of the earth; for I am God, and there is none else.’ (Isaiah 45:21-22, Jonah 3:5-10)
Biblically, people can receive forgiveness of sins through sincere repentance sought directly from God. This is true at all times and in all places. There has never been a need for the so-called inter cessionary role Jesus plays in attaining atonement. The facts speak for themselves. There is no truth to the Christian belief that Jesus died for our sins and salvation is only through Jesus. What about the salvation of people before Jesus? Jesus’ death brings neither atonement from sin, nor is it in any way a fulfillment of biblical prophecy.
Christians claim that in the birth of Jesus, there occurred the miracle of the incarnation of God in the form of a human being. To say that God became truly a human being invites a number of questions. Let us ask the following about the man-God Jesus. What happened to his foreskin after his circumcision (Luke 2:21)?
Did it ascend to heaven, or did it decompose as with any human piece of flesh? During his lifetime what happened to his hair, nails, and blood shed from wounds? Did the cells of his body die as in ordinary human beings? If his body did not function in a truly human way, he could not be truly human as well as truly God. Yet, if his body functioned exactly in a human way, this would nullify any claim to divinity. It would be impossible for any part of God, even if incarnate, to decompose in any way and still be considered God. The everlasting, one God, in whole or in part, does not die, disintegrate, or decompose: ‘For I the Lord do not change.’ (Malachi 3:6)
