“The most important commandment of the Judeo-Christian tradition is to treasure God and his realm more than anything else…That is what it means to love God and with all your heart, soul, mind and strength. It means to treasure him, to hold him and his dear, and to protect and aid him in his purposes. Our only wisdom, safety, and fulfillment lies in so treasuring God.”
Teacher, which is the greatest commandment in the Law?” Jesus replied: “‘Love the Lord your God with all your heart and with all your soul and with all your mind.’ This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself.’ All the Law and the Prophets hang on these two commandments.” Matthew 22:36-40
