"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.'
Matthew 22:36-39 (NIV)

Jesus was clear about what the first and second most important commands are. All of the other articles and videos on this site are an attempt to define what it means to love God and each other.

We use the Bible as our authority on these matters.
