John 13:34-35: “A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.”
A real test if we are Disciples of Christ or not is not in the are of knowledge of the doctrines and specifics of Christian theology, ability to memorize Scriptures, say long prayers, fasting often or evangelizing the unreached. It comes when we have to show love to our brothers in Christ, for those that might have different understanding in terms of theology, for those who have a different social status, different tastes, cultural backgrounds and etc. Love is the ultimate test.
Why? That is the most important thing of all. People search for it. They long for it. They dream about it. They desire love. And that is the final argument that convinces unbelievers in reality of Christ. When they see how we love each other they come to understand that there must be a greater power that inspires us to do that. And this leads them to conversion. Let us set our priorities right. Love and righteousness should be on the top of our lists.
