John 13:34-35

I am giving you a new commandment, that you love one another. Just as I have loved you, so you too are to love one another. By this everyone will know that you are My disciples, if you have love and unselfish concern for one another. 

Every person sitting in the pew on Sunday has quirks, and Jesus recognizes that we may not always be our best selves. However, Jesus still loves us; we should love each other and not be selfish. Love means we are kind, bear with each other, and reciprocate giving and receiving love.
