In this is love, not that we have loved God but that he loved us. John reverses the direction: love does not begin with you. It begins with God. You are loved, that is the starting point, not the result.
When unrest steers you, remember: you do not need to earn or reciprocate God's love to be accepted. The love is already there. And on this love your peace stands, firm, unshakable, because God took the first step.
