If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. ~ 1 Corinthians 13:1
Some men have difficulty expressing love with their words, while most find it natural to express love by their actions. Be mindful of what your actions are saying.
Are your actions telling the people around you - that you love them? Are you showing the light of Christ through your hands, your work, or the things you do for them?
Talk is cheap and actions often do speak louder than words. But there does come a time when we must use words to tell others about why we do the things we do. Because Jesus first loved us... we are moved to love and serve.
