It was in prison the Joseph knew the strength of the Lord.
It was in the lion's den that Daniel's faith was proved.
It was in the furnace that Daniel's three friends found themselves accompanied by a fourth.
We have plenty of "proof texts" - but in order to experience their truth we have to be placed in "proof contexts". The prison, the lions' den, the furnace are where we are shown the realities, incontestably and forever.
~ A Lamp For My Feet by Elisabeth Elliot
