God is love, and those who abide in love abide in God, and God abides in them. Love has been perfected among us in this: that we may have boldness on the day of judgment, because as he is, so are we in this world. There is no fear in love, but perfect love casts out fear; for fear has to do with punishment, and whoever fears has not reached perfection in love. We love because he first loved us. Those who say, “I love God,” and hate their brothers or sisters, are liars; for those who do not love a brother or sister whom they have seen, cannot love God whom they have not seen. The commandment we have from him is this: those who love God must love their brothers and sisters also.
There are all sorts of reasons we humans are sometimes afraid in this life. And some fears are actually helpful, like the fear of making bad decisions or even honest mistakes which can be consequential. How we navigate such makes all the difference, so that hopefully we’re not lost in the grip and paralysis of fear.
What is referred to in this passage of Scripture is the fear of God’s judgment and possibly connected to that, the fear of death itself (click link for Eugene Peterson’s rendering in The Message). These can go hand in hand, though we humans are usually occupied with one concern at a time.
The John writing this is bringing God’s great love, in essence God God’s Self into the picture. That love, the love God is, is made known to us by the Spirit through Christ, something we especially experience as God’s children together, but also in our individual lives as we go about our days.
This love casts out fear no less, the fear which can dominate and actually displace this sense of love from God, the love of God in Christ Jesus. So it’s either this unhealthy, paralyzing fear which can grip us, or the love of God poured into our hearts, one or the other. Though often we can go in and out between. But make no mistake, God’s love wins out in the end even in all things, including death itself.
What John tells us here is that we who know God’s love in Christ and therefore love God, are to love our brothers and sisters in Christ, as well. I’m not sure we’ll ever reach “perfection in love” in this life, though I’m sure we can experience something of that in its fullness at times. But even keeping that in our memory, say from an experience, or experiences along the way, we should proceed accordingly. Refusing to allow our thoughts, actions, and words be dictated by fear, but rather by this love of God for us and for the world. In and through Jesus.
