Blackaby “seems to be in good spirits and lucid,” the Blackaby family said in a statement posted on the Blackaby Ministries International website around 6 p.m. Eastern time Saturday.

Apparently, Blackaby was on his way to pick up his wife Marilynn from an appointment when he suffered a heart attack, according to the statement.

“He did not have his cell phone with him nor insulin for his diabetes,” the statement said. “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 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.”

After Henry Blackaby went missing, his website offered updates on sightings. It also urged readers to pray for his safe return. Twitter was also abuzz with fans encouraging his family and posting updates. Blackaby had been missing since Thursday afternoon after leaving his home near Atlanta. Henry suffers diabetes, and family members feared that he may have been affected by the condition and unable to find his way back home.

Henry Blackaby update: He has been found! Doctors are checking him to see if he is OK, but he is safe. THANK YOU for your prayers!
