"Knowing therefore the fear of the Lord, we persuade men" 2 Cor 5:11
"And he went into the synagogue, and spake boldly for the space of three months, disputing and persuading the things concerning the kingdom of God." Acts 19:8
"And when they had appointed him a day, there came many to him into his lodging; to whom he expounded and testified the kingdom of God, persuading them concerning Jesus, both out of the law of Moses, and out of the prophets, from morning till evening. And some believed the things which were spoken, and some believed not." Acts 28:23
If it's good enough for St Paul it's good enough for me.
