Zimmerman, his family and their supporters have denied allegations of racism and argued that civil rights groups are being incendiary without facts to back up their claims.
"We have a verdict. I think we should really take a step back, respect that verdict, respect those six women -- an all-women jury, who had to make a really tough call and had to look at this outside all the emotions that were stirred up, and all of the racial innuendo that was stirred up, and just kind of look at the facts," Zimmerman's brother, Robert Zimmerman Jr., told CNN on Sunday morning. "And the facts spoke for themselves."
Some applauded the jury for siding with the neighborhood watch volunteer's claims that he shot the teen in self-defense. Others said prosecutors failed to prove their case beyond a reasonable doubt.
Some said the trial was a referendum on race that confirmed what they knew all along.
"That's our society," Terri Weems said as she headed into church in Washington on Sunday morning. "We expected not to be given justice. We haven't been dealt justice all this time. ... It's very disheartening."
Reactions from the pulpit
In churches around the country, the trial was a hot topic on Sunday.
Donna Holmes-Lockett, who was also heading into church in Washington, said she was surprised by the verdict.
Zimmerman should have been punished for the shooting, she said.
"As a mother of black males, I have three sons, it makes me nervous about the reaction of the public toward the situations. I felt like he should have got some kind of, something. He's just walking away free. He did shoot him. It's like it's OK," she said. "I think if it was a black crime on a black person, it would have been a different outcome."
At Ebenezer Baptist Church in Atlanta, the pastor called for all parishioners under 18 years old to step forward in a tribute to Martin.
"The world needs your voice. Don't let anybody tell you that you're a nobody. We love you and we're counting on you," he told them.
"Nobody gets nervous seeing you talk bad and look bad. If you really want to strike fear in the hearts of your adversaries, if you really want to be a real threat, make sure God is in your heart (and) knowledge is in your head."
At churches with close ties to the case, Sunday was a time to reflect and pray.
"We're leaning in and depending on you this morning, oh God, for all of our help," a man said from the pulpit at the Allen Chapel AME Church in Sanford, where a town hall meeting was held after the shooting. "We're not depending on the Sanford Police Department. We're not depending on Seminole County Sheriff. We're not depending on the courts of Seminole County, Florida."
Several members of Martin's family attended services at Antioch Missionary Baptist Church in Opa-locka, Florida.
"We're very concerned, very hurt and very disappointed at this point, but we know in the end God will prevail and justice will be served," said Roberta Felton, a cousin.
While the Martin family grieves, Pastor Arthur Jackson III said, the community must prepare to take action.
"I believe this situation has not paralyzed us, has not traumatized us, but is mobilizing us," he said. "It has been a call to rally at the polls, to vote ... to change these unjust laws."
