The Holy Bible is God himself in writing. To know or understand God, the maker of the universe is to admit,accept and adhere to the the words of the Holy Bible. Gods chosen people is Israel. By the releasing of His only begotten son Jesus, any other person who accepts him as Lord and personal saviour is brought to the commonwealth of Israel being made a one new man in Christ. Entitled to the promises made to Abraham.
The existence of divinity is well captioned in the Holy Scriptures in relation to how God lived among His chosen people Israel. Right from the onset of creation the story gets interesting with people like Noah,Moses,Abraham,the judges,David,Solomon etc. These people though not perfect beings relied on God, obeyed God and decided to follow God no matter how difficult following him is..Jerusalem as been associated with Israel right from the intalment of David as the king of Israel. Jerusalem was established by king David 3000 years ago. His son Solomon was the first to Build a temple in Jerusalem. The rest is History but the Bible has it all. Read your Bible. You will certainly appreciate this whole idea about Israel and Jerusalem.
