Calvary Chapel founder Chuck Smith started chemotherapy treatment this week -- less than a month after announcing to his church that he has lung cancer.
Friends of the 84-year-old senior pastor assured he is in good spirits, but asked for continued prayer.
"Chuck Smith is doing fine. I spoke with him last week and this cancer is not going to separate him from Jesus," Mike MacIntosh, senior pastor of Horizon Christian Fellowship in San Diego, wrote on his Facebook page.
"Please pray for him as he will begin chemotherapy next week and then radiation. He's the all-time great guy and would never complain, so let's [bathe] him in prayer," he added.
Smith, who's well-known for fathering the Jesus People Revolution in Southern California, said he wanted congregants to hear from him exactly what's going on with his health.
"I wanted them to hear it from me and know the confidence that I have in the Lord," Smith told journalist Dan Wooding after making the announcement on New Year's Day.
"Whatever comes, as I said to them on Sunday, the worst thing that can happen is I could die, but that's great you know," he added.
Smith started Calvary Chapel in 1965.
Since then, the church's congregation has grown from 25 to nearly 10,000.
