There are many reasons.

Many reasons why you desire the things that you desire.
Many reasons why you pursue the things that you pursue.
Many reasons why you commit to the things that you commit to.

Some motivations include:

Love.
Peace.
Money.
Progress.
Happiness.
Fulfillment.
Acceptance.
Recognition.
Achievement.

These are all great motivations but, in my experience, they are not enough.

When stress is rising.
When results are lacking.
When obstacles are overwhelming.

Certain motivations just don’t cut it.

When your faith has left you.
When your family has ridiculed you.
When your friends have abandoned you.

Money and happiness do not provide strong enough incentives to persevere.

But there does exist one motivation that trumps the rest.

One motivation that is pure.
One motivation that is supreme.
One motivation that is most noble.

This motivation is…OBEDIENCE.

Obedience to a God who loves you.
Obedience to a God who gave you the vision.
Obedience to a God who provided you the resources to start.
Obedience to a God who has promised to never leave you nor forsake you.
Obedience to a God who put the opportunity in your hands in the first place.

So why, ultimately, should you remain committed to the things that you do?

Because God told you to.

This is obedience.

The most noble of motivation of all.
