Love one another.  In Mark 4 we find the parable of the sower. Jesus said to them, "If you can't understand the meaning of this parable, how will you understand all the other parables?" If we don't wrap our arms around the vital importance of hearing the Word of God and the proper response to it, we won't get anything else. 15 times in the epistles we are told to love one another. And this love is a love that is not based on what we can get from it - but on what we pour into it. It's a love that serves - a love of sacrifice. This is our litmus test - how do we love one another?
