We should remember that saying 'I love you' is only a beginning. We need to say it, we need to mean it, and most importantly we need consistently to show it. We need to both express and demonstrate love.
As we fear God more completely, we love Him more perfectly. And 'perfect love casteth out all fear'.
In the school of mortality, we experience tenderness, love, kindness, happiness, sorrow, disappointment, pain, and even the challenges of physical limitations in ways that prepare us for eternity.
We can begin to become more diligent and concerned at home by telling the people we love that we love them. Such expressions do not need to be flowery or lengthy. We simply should sincerely and frequently express love.
