"why should Israel keep on been afraid and always shiver"
Good question my friend! Maybe the answer is this, your God warned your forefathers that He would scatter them to the 4 winds if they were not obedient to Him. 70 years captivity in Babylon was not enough to teach them obedience, for they then committed the most dreadful sin in rejecting the Lord Jesus Christ, His only begotten Son and put Him to death on the stake. So the good Lord scattered you throughout all nations in AD70 and finally in AD135, exactly as He had warned. (Read Deut 28 - it is chilling stuff) BUT He also promised to regather you back to your land. A process that took decades but in 1948 Israel declared herself an independent nation. The God of Israel has fulfilled His promise and today Judah is back in her own land. Later, under the rulership of the Lord Jesus Christ, Elijah will bring the rest of the tribes to their ancient homeland. So perhaps the answer to your question is that, most of your people (2 thirds it seems) have forgotten that your nation is God's "first born (national) son". Freed from slavery in Egypt by Him some, 3500 years ago. And in a covenant with Him at Sinai promised "all that the LORD hath said, we will do". If you want answers, my friend, go to the Torah. It is all in there. Good luck and may God Bless you.
