9Now concerning love of the brothers and sisters, you do not need to have anyone write to you, for you yourselves have been taught by God to love one another; 10and indeed you do love all the brothers and sisters throughout Macedonia. But we urge you, beloved, to do so more and more, 11to aspire to live quietly, to mind your own affairs, and to work with your hands, as we directed you, 12so that you may behave properly toward outsiders and be dependent on no one. (1 Thessalonians 4:9-12, NRSV)
Love one another.
It really is that easy.
Think of others over yourself, and do what is needed for them to know that God loves them.
Share what you have been given with those in need and help those who need help. If you do this, then it will be done for you too.
How much better would the world be if we all loved each other?
