Experiencing God author, Henry Blackaby, is scheduled to undergo surgery after suffering a heart attack last week, the Baptist Press reports.
The news comes after the 78-year-old went missing Thursday afternoon for more than 24 hours before being found by police 150 miles from his home.
"The Blackaby family would like everyone to know that Henry has been found and is safe," the Blackaby family said in a statement posted on the Blackaby Ministries International website Friday. "His health concerns are being addressed and we will keep everyone posted with the news."
Blackaby had been on his way to pick up his wife Thursday when he suffered the heart attack, became disoriented and ended up in Tifton, Ga.
"He did not have his cell phone with him nor insulin for his diabetes," the Blackaby family explained. "As a result, his blood sugar rose and his kidneys began to struggle as well."
"The family was able to track his movements as he used a credit card to make occasional purchases," the statement read. "The police assigned a detective group to monitor his movements and to track him down. Hundreds of volunteers, many from his church at First Baptist Church Jonesboro, Ga., drove all over the city looking for him. He is currently in a hospital undergoing extensive tests."
Blackaby's son, Richard, says his father's heart is in "bad shape."
"Will need at least 4 bypasses done ASAP," Richard announced Saturday via Twitter. "Please continue to pray. Surgery may be Sunday."
Blackaby, a Southern Baptist minister, is best known world-wide for his best-selling book Experiencing God: Knowing and Doing the Will of God sold more than 7 million copies and was translated into 45 languages.
