In early 2016, I began paying attention to reports about the incredible number of unarmed black people being killed by the police. The posts on social media deeply disturbed me, but one in particular brought me to tears: the killing of Alton Sterling in my hometown Baton Rouge, La. This could have happened to any of my family members who still live in the area. I felt furious, hurt and hopeless. I wanted to do something, but didn’t know what or how to do it.

A few weeks later, during preseason, my teammate Colin Kaepernick chose to sit on the bench during the national anthem to protest police brutality. To be honest, I didn’t notice at the time, and neither did the news media. It wasn’t until after our third preseason game on Aug. 26, 2016, that his protest gained national attention, and the backlash against him began.

That’s when my faith moved me to take action. I looked to James 2:17, which states, “Faith by itself, if it does not have works, is dead.” I knew I needed to stand up for what is right.

I approached Colin the Saturday before our next game to discuss how I could get involved with the cause but also how we could make a more powerful and positive impact on the social justice movement. We spoke at length about many of the issues that face our community, including systemic oppression against people of color, police brutality and the criminal justice system. We also discussed how we could use our platform, provided to us by being professional athletes in the N.F.L., to speak for those who are voiceless.
