“There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love. We love, because He first loved us. If someone says, “I love God,” and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen. And this commandment we have from Him, that the one who loves God should love his brother also.” ~1 John 4:18-21
In relationships, romantic primarily but also platonic, we often have an element of fear entwined, which leads us to the anxiety, butterflies, and other similar apprehension so common to insecure situations. We fear that if we misspeak or fail to act in an expected manner, the other person will reject us. Although this is more of a secondary application of the above passage from 1 John, I believe that the other person’s rejection is the punishment linked to our fear. Consequently, we do not have perfect love, because we are convinced that their love is in some way conditional. And it may be.
