'Preaching' in the Bible

for our good news [regarding salvation] came to you not only in word, but also in [its inherent] power and in the Holy Spirit and with great conviction [on our part]. You know what kind of men we proved to be among you for your benefit.

For our appeal does not come from delusion or impure motives, nor [is it motivated] by deceit [our message is complete, accurate, and based on the truth—it does not change].
