Paul, as an apostle of Jesus Christ, though he was “one born out of due time” (1 Corinthians 15:8), said in 2 Corinthians 11:5, “I consider that I am not at all inferior to the most eminent apostles.”
His apostleship was given directly by Jesus Himself (cf. Acts 9:15-16), and both his own epistles and Luke’s record of his ministry (Acts) attest to the truth of this. But the next words written, in 2 Corinthians 11:6, give a very good reason for Paul’s success, “Even though I am untrained in speech, yet I am not in knowledge.”
There is great reward, both for the teacher and the student, when knowledge is shared. It doesn’t matter if the speech or ability is limited. Paul is proof of this, and expressed it wonderfully through his pen.
Some disagree. Some said about Paul, “For his letters, they say, ‘are weighty and powerful, but his bodily presence is weak, and his speech contemptible.’” (2 Corinthians 10:10). What an inept and inappropriate criticism. What Paul was preaching was the gospel of Christ, “the power of God to salvation for everyone who believes…” (Romans 1:16). The proof is evident.
If you have little talent, but you have studied and know God’s word, share it! Let the power of God come, not by eloquence, but from the scriptures themselves. It is there from whence true power comes!
