"Everybody can be great, because everybody can serve. You don't have to have a college degree to serve. You don't have to make your subject and your verb agree to serve. You don't have to know about Plato and Aristotle to serve. You don't have to know Einstein's 'Theory of Relativity' to serve. You don't have to know the Second Theory of Thermal Dynamics in Physics to serve. You only need a heart full of grace, a soul generated by love." – Rev. Martin Luther King, Jr., 1968

I am blessed that I got to experience the March For Our Lives in Washington D.C. last week in person, blessed that I got to stand in support of the Parkland youth and far too many like them that have become victims of gun violence.

I am an adamant supporter of common-sense gun control, but that's not why I'm writing this article. This applies to everyone, regardless of your political viewpoints.

There's no excuse anymore.

There's no excuse to remain silent about those things you are passionate about.

There's no excuse to simply post on Facebook or Twitter about your indignation.

There's no excuse to only tell your friends about the concerns you have for our nation if you think they are truly crucial to the wellbeing of our future.

There's no excuse anymore because a group of teenagers and even pre-teens just showed us that they can raise their voices just as well if not better than adults.

When high school seniors like Samantha Fuentes, who was just one month ago shot in the leg with an AR-15, can stand in front of hundreds of thousands of people, throw up "on international television," as she put it, and keep delivering one of the most powerful speeches I've heard in my lifetime, we have no excuse.

When Emma Gonzales, 18, can command the attention of hundreds of thousands in the crowd with nothing but silence for those students who were lost in the Parkland shooting, we no longer have any justification for remaining silent ourselves.

When Naomi Wadler, 11 and in fifth grade, gave perhaps the best speech of the entire march, then we no longer have any excuse.

When Martin Luther King Jr.'s own 9-year-old granddaughter, Yolanda Renee King, stood on a stage and declared with passion, "I have a dream that enough is enough" when it comes to gun violence, how can you justify your silence any longer?

Some politicians have tried to posit that these kids are too young to have a political opinion, too young to be taken seriously.

I strongly disagree. The fire that God has stirred in the hearts of these American youth from different corners of the nations, of different races and ages and genders and orientations, is real, and their movement has doesn't seem nearly as ready to flame out. As a Christian, too, I find it fitting that God would use the people that many see as "the least of these" to start a movement.

After a while, the kids simply decided that enough was indeed enough, just as King's granddaughter said. I imagine they were tired of adults promising change, promising safety, and doing nothing about it. And in one month's time, they organized one of the most coherent marches America has seen in a while.

So now, there are no excuses left for any of us to sit on the sidelines. Whatever your passion, it's time to stand up or shut up.
