Though imprisoned for his teachings, he avoided charges of blasphemy by signing a recantation. Robins, a ranter, was a man of little education. By his own account, "As for humane learning, I never had any.
My Hebrew, Greek, and Latine comes by inspiration".
He appears to have been a small farmer, owning some land. Robins probably viewed himself as an incarnation of the divine being.
He asserted that he had appeared on earth before, as Adam, and as Melchizedek. He claimed a power of raising the dead.
Robins put forward a scheme for leading a host of 144,000 persons to the Holy Land.
Joshua Garment was to be his Moses for this expedition. The volunteers were prepared by a vegetarian diet of dry bread, raw vegetables, and water. During three days they held a kind of public reception of the "gentry and citizens" who "resorted thither to dispute with them".
Robins reduced his former claim to one of inspiration, and rested his hopes of salvation on the merits of our Lord.
His followers stoutly maintained his higher pretensions. Robins remained in prison for more than ten months.
On 5 February 1652, Reeve and Muggleton, who had just received their own "commissions" as prophets, visited Robins in his Clerkenwell prison, and passed sentence of eternal damnation upon him. The scene is graphically narrated by Muggleton.
Robins said afterwards that he felt "a burning in his throat", and heard an inward voice bidding him recant.
Accordingly, about two months later, he addressed to Oliver Cromwell, the Lord Protector of England at the time, a letter of recantation, and as a result was freed. Afterwards, he returned to the country, repurchased his land, and lived quietly. Though he professed to expect to "come forth with a greater power", he was not heard of again.
