AE 167 - Truth in will and act

AE 167 [2-3]

Truth in the will
and from that in the act
is what separates and dissipates falsities.
Truth in the will
and from that in the act
is willing and doing
what a man knows and thinks to be true;
such truth is what is especially meant by "reins." 

I, Jehovah, search the heart,
I prove the reins,
even to give every man according to his ways,
and according to the fruits of his works.
(Jeremiah 17:10)

"Searching the heart"
is purifying good by separating evil from it;
"proving the reins"
is purifying truth by separating falsity from it;
it is therefore said
"to give to every man according to his ways,
and according to the fruit of his works;"
"ways" are the truths that are of faith,
and "the fruit of works" are the goods that are of love.
