2 Timothy 3:7 - Learning or Living?

2 Tim 3:7 (KJV)  Ever learning, and never able to come to the
knowledge of the truth.

2 Tim 3:7 (CWB)  These kinds of people listen to anybody.
They're always ready to learn but never come to the point of
acknowledging the truth or fully accepting God's forgiveness.

Ever learning, but loaded with sin and led astray by their
lusts, they never really came to an understanding of the truth.
[Wiersbe Expository Outlines]

Many obtain much speculative acquaintance with the "doctrines"
of Christianity, but never become savingly acquainted with the
system; many study the constitution and government of the church, but
remain strangers to practical piety; many become familiar with the
various philosophical theories of religion, but never become truly
acquainted with what religion is; and many embrace visionary theories, who
never show that they are influenced by the spirit of the gospel.
Nothing is more common than for persons to be very busy and active in
religion, and even to "learn" many things about it, who still remain
strangers to the saving power of the gospel. (Barnes' Notes)

They hear, repeatedly hear, it may be, good sermons; but, as
they seldom meditate on what they hear, they derive little profit
from the ordinances of God. They have no more grace now than they had
several years ago, though hearing all the while, and perhaps not
wickedly departing from the Lord. They do not meditate, they do not
think, they do not reduce what they hear to practice; therefore, even
under the preaching of an apostle, they could not become wise to
salvation. (Adam Clarke Commentary)

This verse is not opposing study and learning; it is warning
about ineffective learning. It is possible to be a perpetual student
and never graduate to putting theory into practice. [Life
Application SB]

He hath scattered the proud in the imagination of their hearts.
Luke 1:51b (KJV)
