Theology and head knowledge are super-duper, but love is supreme. Intellectual debates don’t change lives; love does. Love is supreme; it disarms, it opens hearts, it saves souls. Love is why Christ died for us on the cross. People will only receive the Gospel from Christians who love them as they are with no strings attached.
One of the biggest perceptions non-Christians have towards Christians is that they do not care about them. The Christians simply want them to “get saved” so they can move on to their next “project.” This idea is explored further in unChristian from the Barna Institute. I would highly recommend that book for any Christian serious about reaching out to the modern world around them.
We live in a culture that has largely migrated away from Christianity. This has happened for numerous reasons, many of which are explain in Deliver Us From Evil by Ravi Zacharias. A good question though, is how the Church allowed this to happen. I think one of the biggest problems is the general lack of love in the modern Church. Many Christians seem more focused on being right that doing right. Read “Grace and Truth” for more on this idea.
There were several ways that I learned this, but the way that impacted me the deepest was in the relationships that I formed while I was deployed. I grew to love many of my non-Christian friends and genuinely cared for them. I wasn’t interested in beating them in philosophical or theological arguments, but in simply loving them as they were.
The Gospel is best shared in the context of a loving relationship, not with a complete stranger but with a friend who you know well. It may take years before the door opens between you and a friend, but until them you simply love them. In 1 Thes 2:8 Paul says that they shared their lives with the Thessalonians. That is how we are to love our neighbors.
