'Within' in the Bible

At once perceiving by His spirit that they were reasoning within themselves, Jesus asked them, "Why do you thus argue in your minds?

but they have no root within them. They last for a time; then, when suffering or persecution comes because of the Message, they are immediately overthrown.

Immediately Jesus, well knowing that healing power had gone from within Him, turned round in the crowd and asked, "Who touched my clothes?"

For from within, out of men's hearts, their evil purposes proceed--fornication, theft, murder, adultery,

all these wicked things come out from within and make a man unclean."

Salt is a good thing, but if the salt should become tasteless, what will you use to give it saltness? Have salt within you and live at peace with one another."
