In 1804 a senior colleague reported that "his moral character was perfect and his head a complete magazine."

He was then sent by Bishop Asbury to Baltimore, where he reluctantly went, as he doubted his being suited to city congregations.

Subsequently, he removed to Indiana and settled on a farm near White River, continuing to preach, visit the churches, and attend the Conferences in all parts of the Union.

Indeed, only a year or two before his death he visited the Indian mission work of his denomination west of Arkansas.

Bishop Roberts was involved in all the discussions and deliberations that culminated in the establishment of the Methodist Protestant Church.

He is buried along with his wife on the grounds of United Methodist-affiliated DePauw University, where there is also a residence hall named in his honor.

The Roberts Park Methodist Episcopal Church in downtown Indianapolis is named for him, too.
