18 There is no fear in love. But perfect love drives out fear because fear has to do with punishment. The one who fears is not made perfect in love. ~ 1 John 4:18
We can’t operate in power when we walk in fear. Likewise, we cannot operate in fear if we walk in love. They will know us by our love. Because we love each other, and we love others, even those who hate us and say all manner of evil against us, we must love them still. And the last point is a sound mind.
In other words, God has given us the Spirit of self-discipline, with an implication that this discipline demonstrates prudence and wisdom. We are no longer free to act any old way or react any old way; we have a holy protocol to follow. And when we follow this holy protocol, fear no longer has a hold on us because we are walking in the steps of Jesus surrounded by the Almighty.
Peace. Love. Go Forth and No Fear.
