What is light in 2 Corinthians 12: 8-9 and what is the explanation?

The light in 2 Corinthians 12: 8-9 is that the apostle Paul admits that he has thorns on his body and is often attacked by Satan. The reason is that suffering and trials are often destined for us by the Lord, so that we can experience the grace and power of Christ. It is for this reason that I read the contents in 2 Corinthians 12: 8-9. He prayed to God three times to get the thorn away from him. However, the Lord did not answer his prayer, but told him that the grace of the Lord was enough for him. This is a very important matter. We may also have something like Paul's thorn. We pray to the Lord many times, but the Lord may not really remove this thorn from us. However, as the Lord said to Paul, even if the Lord does not remove it from us, his grace is enough for us, and his power should be complete in our weakness.
