'Lessons' in the Bible

Then He proceeded to teach them many lessons in figurative language; and in His teaching He said,

But these are not the lessons which you have learned from Christ;

If you warn the brethren of these dangers you will be a good and faithful servant of Christ Jesus, inwardly feeding on the lessons of the faith and of the sound teaching of which you have been, and are, so close a follower.

So remember and take to heart the lessons you have received and heard. Keep and obey them, and repent [change your sinful way of thinking, and demonstrate your repentance with new behavior that proves a conscious decision to turn away from sin]. So then, if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.
