Iain Campbell has a great post in which he briefly outlines the labors of three men: Alexander Cruden, Robert Young, and James Strong. You can read it here. Let’s not, in this age of technological advancement, forget the labors of these men who left an enormous blessing behind.
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
