To Be Free

In 1642, Sir Richard Lovelace, then a religious prisoner, wrote the following:
“Stone walls do not a prison make,
Nor iron bars a cage;”
In about 30 AD, as recorded in John 8:32, Jesus said, “You shall know the truth and the truth shall set you free.”
Why would I dare put these two together? Just this: I am moved to wonder how many of us are imprisoned, not in stone walls and iron bars, but in a conscience that will not set us free when, if we would only turn to Jesus and be obedient to Him, we could be free, indeed?
What say ye?
