God will vindicate the truth of His revelation.
His creation and providence signs of His power.
Men’s misfortunes by land and sea are due to their own sins.
The provision of the next world is best for the righteous.
It is not sinful to retaliate if wronged, though forgiveness is a duty.
The sinners shall have none to help them on the Day of Judgement.
They are exhorted to repent before it comes.
Ingratitude of man.
God controls all.
No mortal has ever seen God face to face.
