Jeremiah 8:9

For tho' the doctrine of the cross seems folly to those that perish: yet we that are to be saved, do feel its energy is divine.

and that from your infancy you were acquainted with the sacred writings, which point you the way to salvation, by believing in Christ Jesus:

Treasury of Scripture Knowledge

The wise men are ashamed, they are dismayed and taken: lo, they have rejected the word of the LORD; and what wisdom is in them?

for consider, brethren, that not many worldly wise, not many men of power, not many men of birth are among you that are called.

For tho' the doctrine of the cross seems folly to those that perish: yet we that are to be saved, do feel its energy is divine.

and that from your infancy you were acquainted with the sacred writings, which point you the way to salvation, by believing in Christ Jesus:

take care therefore, that the light which is in thee do not become darkness.

pretending to be wise, they became fools:

for it is written, "I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent."
