The greatest objective you can have in life is to live for something. The greatest objective you can have in life is to live for someone. The greatest objective Jesus had was to live for others. His life was lived for others.
There is nothing actually greater than living your life for other people. It gives you a heart of hope and joy and expectation, strength and encouragement that the life you are living, you are living to meet up to other people's need, want and heart desires. You become a solution to someone's problem, an answer to other people's questions.
When you live your life for others, you own life is in turn preserved in the hands of God.
