Which is greater: The ability to speak well or to gain knowledge? We cannot deny the power of someone who has great skill in speaking, but if he does not know the truth, what good are his speaking skills?
Therefore, knowledge is greater. Paul said,
“Even though I am untrained in speech, yet I am not in knowledge. But we have been thoroughly manifested among you in all things” (2 Corinthians 11:6).
Yes, learn to speak well, whether publicly or one-on-one, but seek the knowledge of the truth first.
