ya, and putting 3 pennies in a kids hand and taking away 1 while asking them how many are left is destructive to their ego as well huh? Instead of it having the potential to properly educate and inform them of basic normal math....I suppose that's where they learn to steal and claim things that aren't rightfully theirs.
A concordance is a very useful tool when one is actually emmersing themselves in Gods word and seeking to understand what is wrote themselves. Instead of ALWAYS relying on what others think and "interpret". Can and do people take it past its limits and proper usage- yes. Though that doesn't mean we should not use one without many years of schooling. Ask around in just the eschatology forum- you'll see and hear many "schooled" individuals with insane interps and ideals. A usage of a bible with aconcordance is a great way to see and check that "teachers" are "accurately" preaching the word of God and not a "feel good" sermon.
