I recently heard this phrase and I really like it. Someone said, "If you have a pulse, you have a purpose." If you are breathing today, if you are alive today, there is purpose in your life. If you are working with people, if there's someone around you today, you have the opportunity to encourage and serve that person. If you can serve another person, you have purpose in life!
Life wasn't meant to be garnered for self. Life is not given to us to horde and control. Life was meant to be given away in love. If there's someone in your sphere of influence, you can love. And if you can love, your life has purpose.
Therefore, let me end with how I began: "If you have a pulse, you have a purpose."
I'd guess if you're listening to this moment of hope, you have a pulse! Now go accomplish your purpose.
