"Now as touching things offered unto idols, we know that we all have knowledge. Knowledge puffeth up, but charity edifieth." KJV
Virtually anything in our lives can become an idol when we allow it to come before God. It is very telling that God commanded the Israelites to, ". . . love the LORD thy God with all thine heart, and with all thy soul, and with all thy might" (Deuteronomy 6:5 KJV). This truth comes full circle in the New Testament when in John 13:34 Jesus proclaims, "A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another." The modern word charity is derived from the Greek feminine noun Charis, meaning: "Grace, that which affords joy, pleasure, delight, sweetness, charm, loveliness: grace of speech" (http://www.searchgodsword.org/lex/grk/view.cgi?number=5485 ).
Knowledge in and of itself is not necessarily a bad thing; although, if our knowledge vaunts itself against God rather than bringing ourselves and others closer to Him it is nothing but a worthless idol. A tin god that can neither hear nor see. God values love, it was His first intention and that hasn't changed. Love God with all your heart, soul and might, not because He commanded it, but because He reached across eternity for you and sacrificed His Son for your release.
