Again, basically, I agree. However, that doesn't do anything to refute by statement that one cannot truly prophesy except by the Holy Spirit, while on can truly preach or teach without the Holy Spirit, for the message is the truth, and the word of God has power. So, let's not get any further off topic.
If you want to open a new Thread and discuss "prophesy" by the Holy Spirit, then that is good, as in this Thread, the verses the OP used explained that it was not Timothy who was uttering the prophesy, but that one was uttered by someone, concerning Timothy.
This led to "what is Timothy's" gift, as a sub topic.
