Matthew 24:12 And because lawlessness will abound, the love of many will grow cold.I came across this article in yahoo, "In God we trust, maybe, but not each other." It describes how Americans have lost their trust in fellow Americans for the past 20 years. In 1972 most Americans said 46% of people can be trusted, it went down to 32% in 2012. The Olivet Discourse immediately jumped to mind, specially the phrase "the love of many will grow cold."
Am not sure if the love indicated in Matthew 24:12 includes trust but the common notion of love does include trusting the one we love. Based on the result of that research, love is indeed growing cold.
Reasons for the decline in trust include less personal interaction, economic inequality, decline in moral values, and greed. All of these issues are covered in the Olivet Discourse. The article stated that being in front of the monitor or TV most times isn't helping.
