To understand the meaning of life is to know first the purpose of our existence as well as the duties that we have to fulfill. And it is in fulfilling our duties and in serving our purpose that our lives become meaningful.

As humans, our purpose and our whole duty is to serve God. That duty is what gives meaning to our lives — without it, our lives become purposeless and meaningless. So, if we want our lives to be purposeful and meaningful, we have to spend it in serving God. And serving God means honoring Him and keeping His commandments.

May God bless you!
