There is a transcendent reality that largely goes unrealized when it comes to go out and proclaim the truth of Jesus Christ. The reality is this; there is a risk involved in loving people. When you consider what Paul was going through in Acts 21, he was being accused and smeared by his detractors, who in turn stirred up crowds against him and put his life in danger. The lesson here is this; it is a risk to love others who might reject us, hate us, and attack us. And to think that the Gospel, and our rescue from Hell, wouldn't exist if God didn't love us, and empower people like Paul to obediently spread that message makes it clear that love drives people (like Paul then and us today) to give it up, take the risk, pay the cost, and despite the cost and obstacles stacked against us, reach out to people anyway. This in turn adds greater power, in a convicting way, to what Jesus talked about when he said to "love your enemies and pray for those who persecute you (Matthew 5:44)."
