Life is made up not necessarily of great sacrifices or high-level duties but of little things. The smiles, the kindnesses, the commitments and obligations and responsibilities that are given habitually and lovingly are the blessings that win and preserve the heart and bring comfort to one's self as we as to others. This is the ministry of service performed by every useful life.
The air we breathe is necessary to keep us alive, but we must continually breathe it out so we can breathe fresh air back into our lungs. God gives us his love, which we can keep in action by breathing it out to others, thus making room in our hearts for a fresh supply of love.
Most people think of love as some sort of power outside of themselves that will "take them away from all of this." Sadly, this is not the case. Love exists only within our own hearts, and to have happy relationships we must first become truly loving people. And as we fill our hearts with love by expressing love for others in thought, word, and deed ("acting as if" until we make it happen if necessary), that love can heal our own lives, help to solve our problems, and enable us to feel good about ourselves.
