"And this is His command: to believe in the name of his son, Jesus Christ, and to love one another as he commanded us." - 1 John 3:23
"Owe no one anything, except to love each other, for the one who has loved has fulfilled the law." Romans 13:8
“You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, Love your enemies and pray for those who persecute you, so that you may be sons of your Father who is in heaven. For he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust. For if you love those who love you, what reward do you have? Do not even the tax collectors do the same?
"Teacher what 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."
It's so simple. To love and to believe. We make all these rules about how to be perfect and better, but often only make ourselves more self-righteous and harder to love because we are imperfect and certainly not better. Just love. love love love love. When I remember this I feel so joyful! Jesus surrounded himself with tax collectors and prostitutes and loved them without judging.
Though it's simple to understand, love is not easy. Loving people that are hard to love is really hard and I think that is why we sometimes try to find or create so many other ways to Christ and avoid just pouring ourselves fully into love. But it is the most important thing.
