“And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.”
King James Version (KJV)
Ac 8:37 If thou believest, etc.? This verse is omitted in the Revised Version. It is not found in the oldest extant manuscripts, but was certainly in manuscripts older than any now extant. It is referred to by Irenaeus in the second century, and by Augustine in the fourth. Whether written by Luke or not, it shows that the custom of the early church was to require such a confession of faith. With all thine heart. A living faith must seize upon and control the heart.
