Job in the book of Job had seen much good in this life, and was a respected and successful rancher, by any standards, ancient or modern. Also he was a godly man, and was indeed protected by God, as is pointed out in Job 1:10. Despite that, Job’s long discussion with his friends deals with many of the troubles and injustices of life.

“Man, who is born of a woman,
Is of few days, and full of trouble.”
Job 14:1

Or again,

“But man is born to trouble,
As the sparks fly upward.”
Job 5:7

Jesus spoke of the ordinary cares and worries of life

“That which fell among the thorns, these are those who have heard, and as they go on their way they are choked with cares, riches, and pleasures of life, and bring no fruit to maturity.”
Lk 8:14

What is Jesus talking about here? The ordinary ups and downs of life. These things are often self inflicted, much as it is for you and I. Not all of it, but some of it is about our choices.

“41 Jesus answered her, “Martha, Martha, you are anxious and troubled about many things, 42 but one thing is needed. Mary has chosen the good part, which will not be taken away from her.”
Lk 10:41-42

Scripture does not promise we will have no troubles

Jesus as a man had troubles. In the end, though innocent, He was condemned to die in courts rigged by the leaders of the Jews. Also He had deep compassion for those having troubles.

“When Jesus therefore saw her weeping, and the Jews weeping who came with her, he groaned in the spirit, and was troubled,”
Jn 11:33

Much as it would be for us, Jesus was personally troubled by Judas unwarranted treachery.

“When Jesus had said this, he was troubled in spirit, and testified, “Most assuredly I tell you that one of you will betray me.” ”
Jn 13:21

He was tested in all points are we are, Heb 4:15.

None of these things can overcome us in Christ.

“35 Who shall separate us from the love of Christ? Could oppression, or anguish, or persecution, or famine, or nakedness, or peril, or sword? 36 Even as it is written, “For your sake we are killed all day long. We were accounted as sheep for the slaughter.” 37 No, in all these things, we are more than conquerors through him who loved us.”
Rom 8:35-37

Jesus also acknowledges that we will have trouble because of our faith. To what end does He instruct us?

“I have told you these things, that in me you may have peace. In the world you have oppression; but cheer up! I have overcome the world.”
Jn 16:33

So He says to us,

“… Don’t let your heart be troubled, neither let it be fearful.”
Jn 14:27

All of this is for sure prophetic instruction. Teaching about how it will be for you and I in the world. Believing what God says in prophecy does matter! It is an ethical matter.
