Mat 7:12 "Therefore, whatever you want men to do to you, do also to them, for this is the Law and the Prophets.
God is love, and since the creation of man, God showed His love to Adam and Eve and also to all their descendents.
Enoch pleased God so much that He took him back to be with Him without Enoch tasting the pain and fear of death. Similarly, all Christians who love Him by keeping His words will not taste death.
John 8:51-52 Most assuredly, I say to you, if anyone keeps My word he shall never see death." Then the Jews said to Him, "Now we know that You have a demon! Abraham is dead, and the prophets; and You say, 'If anyone keeps My word he shall never taste death.'"
Deu 9:7 "Remember! Do not forget how you provoked the Lord your God to wrath in the wilderness. From the day that you departed from the land of Egypt until you came to this place, you have been rebellious against the Lord."
God loved the Israelites and ensured that when they were brought out from Egypt they saw His power of making Pharaoh to set them free, parting the Red Sea and the destruction of the whole Egyptian army. They also saw His ability to feed the two million souls in the wilderness for forty years.
God gave them the Mosiac Law so that they had no excuse that they were not aware of sin. Out of His great love for the Israelites, He dwelled amongst them. He encouraged them to believe and love Him and to keep the Law by allowing them to see a column of cloud in the day and a column of fire at night above the tabernacle of God during His presence.
Yet they murmured and rebelled against Him and even threatened to kill Moses.
Jer 5:23, 30-31 But this people has a defiant and rebellious heart; they have revolted and departed... "An astonishing and horrible thing has been committed in the land: The prophets prophesy falsely, and the priests rule by their own power; and My people love to have it so. But what will you do in the end?"
The final straw came when the rebellious Israelites loved lies of the false prophets and the abominations committed by the priests. So God allowed the Babylonians to raze Jerusalem and the temple of God to the ground and the complete destruction of Israel.
Similarly in the last days, if Christians have lost their love for God and for brethren by becoming worldly, covetous, carnal and wicked and are rebellious to His words by believing lies and false prophecies and accepting wrong doctrine and heresies, then God will allow World War 3 to judge Christians.
2Tim 4:3-4 For the time will come when they will not endure sound doctrine, but according to their own desires, because they have itching ears, they will heap up for themselves teachers; and they will turn their ears away from the truth, and be turned aside to fables.
How the Jews can love God?
The Jews, who love God, must keep His commands, which are easy to keep if they really love Him. Two samples :-
'love your neighbours but hate your enemies' or 'an eye for an eye and a tooth for a tooth'
Our Lord Jesus told us that for the Jews to fulfill the Law and Prophets they only need to do this; 'whatever you want men to do to you, do also to them' which is the sign of care, compassion and love for one's neighbour (friend). The Jews were so selfish, stiff-necked, covetous and merciless that they do not even care for their friends. They may look religious but they do not love God. No wonder, Jews are generally known for being shrew and merciless concerning money.
