Did God continue the Abrahamic covenants through Isaac or Ishmael?

The Abrahamic covenants continued through Isaac, the promised son, not through Ishmael. The promise given to Abraham specified that the covenant line would pass through Isaac, whom God designated as the child of promise, rather than through Ishmael, the son born according to the flesh.

Les teaches that the promise to Abraham was that the covenants would continue, not through Ishmael, but through the promised son, Isaac. He notes this as a continuation from the previous program, reminding viewers that this is an informal Bible study. The context presents Isaac as the promised son through whom the covenant line would continue, while Ishmael is explicitly excluded from that covenant continuation.
