'Stimulating' in the Bible

For you know how we were exhorting and encouraging and imploring each one of you just as a father does [in dealing with] his own children, [guiding you]

He must hold firmly to the trustworthy word [of God] as it was taught to him, so that he will be able both to give accurate instruction in sound [reliable, error-free] doctrine and to refute those who contradict [it by explaining their error].
