He said to him, “Love the Lord your God with all your heart, with all your soul, and with all your mind. This is the greatest and most important command. The second is like it: Love your neighbor as yourself.  All the Law and the Prophets depend on these two commands.”
Matthew 22:37-40 (HCSB)

In this statement by our Lord Jesus lies the one and only answer to our world's problems. It must start within the heart and conduct of His people.
