AR 564 - the truth of the church should be seen, in order that it may be believed

AR 564
How can any person be led by the Lord,
and conjoined with heaven,
who shuts up his understanding
in such things as relate to salvation and eternal life?

Is it not the understanding which will be enlightened and taught?

Is not religion to shun evil and do good?

Must not the doctrine of the church teach this,
as also what a person should believe,
that he may do the good works of religion from God?
