Holy Bible (scripture)
The original scripture whether in Hebrew, Aramaic, or Greek was inspired, inerrant, and infallible. This means God spoke the words to men and all of it was without error and true including punctuation. Copies were made of the originals as they wore out and the originals no longer exist. God has preserved his word in English in the King James Bible (Authorized Version) which is also inspired, inerrant, infallible and all of the punctuation and pilcrows [paragraph markings which properly end with Acts 20:36] are correct and inspired. All of the scripture was given to us in the 66 books of the King James Bible, no more and no less with exactly the verses as in the King James Bible. The chapter and verse numbers in the King James Bible are also inspired. The King James Bible is scripture (word of God) and is the final authority on all matters. (II Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:)
God
God is one God in three persons (God the Father, God the Son [Jesus], and God the Holy Ghost). This is known as the Godhead.
Jesus
Jesus is the second person in the Godhead and the only begotten Son of God the Father. He as God has always existed. He is the Creator and Sustainer of life and the universe. Jesus came to earth in the flesh as a man to be the Saviour of mankind. He was born of the virgin Mary by the Holy Ghost. Jesus lived a sinless and perfect life. He preached to the lost, performed miracles, died on the cross for mine and your sins and the sins of everyone who has or ever will live. Jesus gave his life for us. No man took it. He was buried and rose again on the third day and is seated at the right hand of God the Father. Jesus will return again for all those who are saved and will reign for a literal thousand years as King of kings and Lord of lords. (Millennium) Jesus is the Jewish Messiah. Jesus is the Word of God.
Holy Ghost
The Holy Ghost is the third person of the Godhead and is just as much God as God the Father and Jesus Christ. The Holy Ghost is the one who convicts sinners of their need to be saved and to call upon Jesus to save them. The Holy Ghost lives within believers.
Man
All people, whether male or female, rich or poor, Jew or Gentile, or any other division are born with a sin nature because of the sin of Adam and therefore must be saved (born again) to have eternal life. People must call upon Jesus to save them. Man (Adam) was originally made of the dust of the ground in the image of God with Eve made from one of Adam’s ribs. After the sin of Adam, all people today are now made in the image of Adam. Man was made a triune being with a soul, spirit, and body. See Why we must be born again.
Salvation
All mankind needs to be saved in order to have eternal life due to the sin nature they are born with. One must admit they are a sinner in need of a Saviour and must call upon Jesus to save them. Salvation is a free gift from God that is received by faith alone. Works will not save you or get you to heaven. All people will spend eternity in either heaven or hell. The saved will be resurrected to heaven and the unsaved (lost) to an eternal damnation in the lake of fire. (John 3:16 ¶ For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.) See What must I do to be saved (be born again), have eternal life and go to heaven? If a person is truly saved, they cannot lose their salvation. Jesus secures it forever. Once saved, always saved.
Jews
The Jewish people are God’s chosen people descendant from Abraham. They are still a part of God’s plan and have not been replaced by the church. All Jews still need to be saved the same way as all Gentiles. The Jews are the only people that have been promised a certain land. (Promised Land) (Israel) One day all of it will be theirs. The Jews are the ones who wrote the scripture and gave to us. Jesus was a Jew and is the Jewish Messiah. Jews are to be prayed for and blessed. God said if you bless Israel, he will bless you and if you curse Israel, he will curse you. Israel has a right to exist.
Church
The church consists of all believers who are saved since the time of Acts. The church is the people and not a building. All true believers regardless of denomination are part of the church. The church is the bride of Jesus. The church is responsible for spreading the gospel to win souls and to teach all nations.
Earth
The earth is a special creation by God made for man. It is special from all other planets. The earth is the only planet with life. The earth was created a little less than six thousand years ago in six literal 24 hour days. Mother nature is not the earth, it is just nature and God the Father. The earth is round and not flat. The earth is not to be worshipped.
