You see, if you repent of your sin, you have nothing to worry about.
Jon 3:5 So the people of Nineveh believed God, and proclaimed a fast, and put on sackcloth, from the greatest of them even to the least of them.
Jon 3:6 For word came unto the king of Nineveh, and he arose from his throne, and he laid his robe from him, and covered him with sackcloth, and sat in ashes.
Jon 3:7 And he caused it to be proclaimed and published through Nineveh by the decree of the king and his nobles, saying, Let neither man nor beast, herd nor flock, taste any thing: let them not feed, nor drink water:
Jon 3:8 But let man and beast be covered with sackcloth, and cry mightily unto God: yea, let them turn every one from his evil way, and from the violence that is in their hands.
Jon 3:9 Who can tell if God will turn and repent, and turn away from his fierce anger, that we perish not?
Jon 3:10 And God saw their works, that they turned from their evil way; and God repented of the evil, that he had said that he would do unto them; and he did it not.
Mat_12:41 The men of Nineveh shall rise in judgment with this generation, and shall condemn it:
because they repented at the preaching of Jonas; and, behold, a greater than Jonas is here.
Nineveh repented and forsook their rebellion.
Luk 15:7 I say unto you, that likewise
joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.
Luk 15:10 Likewise, I say unto you,
there is joy in the presence of the angels of God over one sinner that repenteth.
Luk 15:11 And he said, A certain man had two sons:
Luk 15:12 And the younger of them said to his father, Father, give me the portion of goods that falleth to me. And he divided unto them his living.
Luk 15:13 And not many days after the younger son gathered all together, and took his journey into a far country, and there wasted his substance with riotous living.
Luk 15:14 And when he had spent all, there arose a mighty famine in that land; and he began to be in want.
Luk 15:15 And he went and joined himself to a citizen of that country; and he sent him into his fields to feed swine.
Luk 15:16 And he would fain have filled his belly with the husks that the swine did eat: and no man gave unto him.
Luk 15:17 And when
he came to himself, he said, How many hired servants of my father's have bread enough and to spare, and I perish with hunger!
Luk 15:18
I will arise and go to my father, and will say unto him, Father, I have sinned against heaven, and before thee,
Luk 15:19
And am no more worthy to be called thy son: make me as one of thy hired servants.
Luk 15:20
And he arose, and came to his father. But when he was yet a great way off, his father saw him, and had compassion, and ran, and fell on his neck, and kissed him.
Luk 15:21 And the son said unto him, Father, I have sinned against heaven, and in thy sight, and am no more worthy to be called thy son.
Luk 15:22 But the father said to his servants,
Bring forth the best robe, and put it on him; and put a ring on his hand, and shoes on his feet:
Luk 15:23 And bring hither the fatted calf, and kill it; and let us eat, and be merry:
Luk 15:24 For this my son was dead, and is alive again; he was lost, and is found.
And they began to be merry.
The prodigal son repented and forsook his rebellion.
Indeed it is a very simple message.
