'Winsome' in the Bible

Finally, believers, whatever is true, whatever is honorable and worthy of respect, whatever is right and confirmed by God’s word, whatever is pure and wholesome, whatever is lovely and brings peace, whatever is admirable and of good repute; if there is any excellence, if there is anything worthy of praise, think continually on these things [center your mind on them, and implant them in your heart].

Let your speech at all times be gracious and pleasant, seasoned with salt, so that you will know how to answer each one [who questions you].
