It's hard to live your life waiting on a phone call, but Billy Click has been doing just that for the past five years.
"It's always the anticipation. You never know. Today could be the day," he said.
He has been waiting for a call telling him a life-saving kidney was available for an organ transplant. He needs a new one.
"Once it started declining there was no stopping," he said.
And because it is so tough to wait on a phone call for five year, Click turned to a higher power.
"I left it in God’s hands, he would provide a way I just had to be patient and steadfast in prayer."
And he delivered in the form of Sunday School teacher Tracy Brewer.
Her husband Mike leads Click's Sunday School class at Dotson Memorial Baptist Church in Maryville.
"We know each other, but it's not really well. But we know each other," she said.
She prayed for Billy along with the rest of the congregation. But then she did something else.
"For some reason I asked him what his blood type is and he told me and that was the moment God spoke to me," she said. "I truly believe because we have the same blood type. It's O positive."
She went through a month of testing without saying a word until she knew it was a match.
"She just came out of the blue. Just like an angel descended and answered my prayers," Click said.
When Brewer took Click and his wife aside to tell them the good news last month, he was stunned.
"I had to back up against the wall to keep my knees from buckling because it just overwhelmed me that much."
They say its divine intervention.
"I knew God had a hand in this. He answered my prayer, the prayer of my church and of my family," Click said.
And when it comes to the surgery later this week, they trust they're in good hands.
"God's got this," Brewer said. "We'll just let God take over from here."
