- The Bible
The preservation of Israel is proof God is real.
The preservation of the God's written Word proves God is real.
God would never allow either to be destroyed. The Bible cannot be destroyed because God has preserved it for thousands of years. Israel cannot be destroyed because God preserved it to set up His Kingdom there.
Only God could preserve Israel through worst Anti-Semitic conditions known to humanity. Only God could preserve a Bible that is hated, tossed aside, and misunderstood more than any other document in the pages of history.
God is real and has put Christ in control of time and eternity. Be ready for His calling out of the Church - which is just like the days of Noah. Be ready because God is real and Christ is soon going to allow His Church to escape the destruction that's coming.
Proof and evidence. Simple.
