King David declared Jerusalem to be the capital of Israel (City of David- 2 Sam. 5).
Legally documented in 1950, the Jerusalem Law was passed by the
Israel Knesset, declaring Jerusalem to be the eternal, undivided capital of the state of Israel.
In 1995, Democrat President Bill Clinton signed a statute stating, "Since 1950, the city of Jerusalem has been the capital of the state of Israel." Bush and Obama reconfirmed that but failed to act.
Christianity begins in Jerusalem serving as the context for Jesus' life and earthly ministry.
The Temple Mount in Jerusalem is where Jesus' return is expected.
