Love is a powerful emotion and an even more powerful choice. We can overcome prejudice, weakness, and fear when we choose to love. The problem is, we can also twist love to mean something it isn't. In Greek, there were four words for love, whereas in English, love comes in only one word. To say it another way, the Greeks would disagree that love is love.
This is just the top of the way people often look at love. One big idea that has been promoted is that love unites and hate divides. This sounds really great, but it falls short on real examination. Looking at scripture and history, I could say just as easily that Hate unites and love divides.
God is love, but it is clear that doesn't mean that he tolerates sin in his presence, a separation. Jesus showed love, but he too spoke of people being divided from God. Shockingly, Jesus also said in Matthew 10:34-36, “Do not suppose that I have come to bring peace to the earth. I did not come to bring peace, but a sword. For I have come to turn a man against his father, a daughter against her mother, a daughter-in-law against her mother-in-law, -- a man’s enemies will be the members of his own household." If that isn't division, I don't know what is.
Often, people think that love means we don't correct or disagree. The Bible speaks of love motivating God to discipline us and tell us we need to change. Which, in the West, isn't called loving. However, even in The Prince by Niccolo Machiavelli (a very un-Christian political theorist) says it's better to be feared than loved because someone can love you and not obey or even work against you because of that love. Love doesn't leave us as we are and it can divide.
Hate, on the other hand, can divide, but it can also unite. Nothing unites people like a common enemy. WW2 brought together people who despised each other so they could fight against someone they hated. Even the "Love unites" (meaning, celebrate me even if it's a sin) groups are often united in hate against those who disagree with them.
Jesus speaks of what seems to be a paradox in many people's minds. He says love your enemies, but also to choose Him over family, money, and power. He wants unity in his body according to Scripture, but also for us to be separate from the world without being separated from the world. The Scriptures say that hate towards people destroys and that human anger doesn't produce the righteousness of God. Yet, we are to hate the world's system and our own sin. If we want to define love as tolerance, then what the Bible says doesn't make sense, but when we see love as a choice to seek the best in ourselves and others, then it does.
Let's define love and hate in God's way.
