Abundance is realizing what you already posses that no money could buy: joy, love, peace and freedom.
Early in our marriage, my husband included in his prayers this verse, Proverbs 30:8 "Remove far from me vanity and lies: give me neither poverty nor riches; feed me with food convenient for me." Truly the Lord has honored that in his life. We always have "enough". At times I do feel discontent, but always the issue comes down to my attitude, not the situation.
Deceivingly, our society has led us to define our abundance by comparison. Then the extremely rich, unnaturally beautiful, and uniquely successful are paraded in front of us on every TV, magazine and media - truly "vanity and lies". Even the most stout at heart can fall victim to comparison.
