Writer and speaker Lewis Smedes says:

Yes, somewhere people still make and keep promises. They choose not to quit when the going gets rough because they promised once to see it through. They stick to lost causes. They hold on to a love grown cold. They stay with people who have become pains in the neck. They still dare to make promises and care enough to keep the promises they make. I want to say to you that if you have a ship you will not desert, if you have people you will not forsake, if you have causes you will not abandon, then you are like God.

What a marvelous thing a promise is! When a person makes a promise, she reaches out into an unpredictable future and makes one thing predictable: she will be there even when being there costs her more than she wants to pay. When a person makes a promise, he stretches himself out into circumstances that no one can control and controls at least one thing: he will be there no matter what the circumstances turn out to be. With one simple word of promise, a person creates an island of certainty in a sea of uncertainty.

When a person makes a promise, she stakes a claim on her personal freedom and power.

When you make a promise, you take a hand in creating your own future.
