In John 13:34-35, Jesus instructed us—His followers—to love others: "A new command I give you: Love one another. As I have loved you, so you must love one another. By this all men will know that you are my disciples, if you love one another." As Christians, learning to walk in love should be a very high priority.
Unfortunately, we often love others only superficially—that is, we talk love, but don't live love. James 2:15-16 addresses this problem: "Suppose a brother or sister is without clothes and daily food. If one of you says to him, 'Go, I wish you well; keep warm and well fed,' but does nothing about his physical needs, what good is it?"
If you say that you love someone, but don't express it by what you do, then that "love" is worthless. Indeed, it isn't even real love.
Likewise, 1 John 3:17-18 asks, "If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him? Dear children, let us not love with words or tongue but with actions and in truth." Here again, we are instructed to love with actions—not just with our mouth.
Follow the instructions of Jesus: love one another. However, remember that real love must be accompanied by actions, because love unexpressed is not love at all.
