Thank you for asking a question on www.thisisyourbible.com
You begin with a misunderstanding - ‘if Jesus is supposed to protect his people’.
The gospel preached by Christ carries no such guarantee. If Christians had the active protection you suggest then all men would be Christians for the wrong reason.
Those who believe the gospel and are baptised into Christ are under no such illusion.
Matthew 23:17 But beware of men: for they will deliver you up to the councils, and they will scourge you in their synagogues; 18 And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles... 21 And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death. 22 And ye shall be hated of all men for my name’s sake: but he that endureth to the end shall be saved.
Matthew 23:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell (hades – the grave). 29 Are not two sparrows sold for a farthing? and one of them shall not fall on the ground without your Father. 30 But the very hairs of your head are all numbered. 31 Fear ye not therefore, ye are of more value than many sparrows. 32 Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. 33 But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.
34 Think not that I am come to send peace on earth: I came not to send peace, but a sword. 35 For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. 36 And a man’s foes shall be they of his own household. 37 He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me. 38 And he that taketh not his cross, and followeth after me, is not worthy of me. 39 He that findeth his life shall lose it: and he that loseth his life for my sake shall find it.
John 16:1 These things have I spoken unto you, that ye should not be offended. 2 They shall put you out of the synagogues: yea, the time cometh, that whosoever killeth you will think that he doeth God service. 3 And these things will they do unto you, because they have not known the Father, nor me. 4 But these things have I told you, that when the time shall come, ye may remember that I told you of them.
James 5:6 Ye have condemned and killed the just; and he doth not resist you.
The Jews had killed the prophets that God had sent unto them.
Matthew 23:29 Woe unto you, scribes and Pharisees, hypocrites! because ye build the tombs of the prophets, and garnish the sepulchres of the righteous, 30 And say, If we had been in the days of our fathers, we would not have been partakers with them in the blood of the prophets. 31 Wherefore ye be witnesses unto yourselves, that ye are the children of them which killed the prophets. 32 Fill ye up then the measure of your fathers. 33 Ye serpents, ye generation of vipers, how can ye escape the damnation of hell (Gehenna – destruction)? 34 Wherefore, behold, I send unto you prophets, and wise men, and scribes: and some of them ye shall kill and crucify; and some of them shall ye scourge in your synagogues, and persecute them from city to city: 35 That upon you may come all the righteous blood shed upon the earth, from the blood of righteous Abel unto the blood of Zacharias son of Barachias, whom ye slew between the temple and the altar. 36 Verily I say unto you, All these things shall come upon this generation.
They caused Christ himself to be put to death by the Romans. The apostles were put to death and many Christians have died for their beliefs down the centuries.
The hope of the Christian is not salvation in this life (for we must all die at some point) but resurrection from the dead to eternal life when Christ returns.
Until Christ returns Christians suffer like all other people. They have no special protection from disease, accidents and death in whatever form it comes.
They are prepared to suffer all things for the life which is to come.
Acts 21:13 Then Paul answered, What mean ye to weep and to break mine heart? for I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus.
Romans 8:35 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? 36 As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. 37 Nay, in all these things we are more than conquerors through him that loved us.
2 Corinthians 4:11 For we which live are alway delivered unto death for Jesus’ sake, that the life also of Jesus might be made manifest in our mortal flesh.
Colossians 3:4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory.
Paul explains what will happen.
1 Corinthians 15:19 If in this life only we have hope in Christ, we are of all men most miserable. 20 But now is Christ risen from the dead, and become the firstfruits of them that slept. 21 For since by man came death, by man came also the resurrection of the dead. 22 For as in Adam all die, even so in Christ shall all be made alive. 23 But every man in his own order: Christ the firstfruits; afterward they that are Christ’s at his coming. 24 Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power. 25 For he must reign, till he hath put all enemies under his feet. 26 The last enemy that shall be destroyed is death. 27 For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him. 28 And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
The gospel is called ‘the gospel of the kingdom of God’ because it is concerned with the kingdom that Christ will set up on the earth when he returns.
I hope you have found this helpful.
