New Blood

In bone marrow transplantation, something remarkable happens that most people never consider. When a patient with leukemia receives a donor's bone marrow, the transplant does not just treat the disease — it replaces the patient's entire blood-producing system. Within weeks, every new red blood cell, white blood cell, and platelet carries the donor's DNA, not the patient's own.

In documented cases, the patient's blood type literally changes. A person who was Type A their whole life becomes Type O. Hematologists call this full donor chimerism — carrying another person's genetic identity within your own body. The old blood-forming cells are gone. The new ones belong to someone else entirely.

Paul wrote to the Corinthians, "If anyone is in Christ, the new creation has come: The old has gone, the new is here" (2 Corinthians 5:17). That was not mere poetry. That was spiritual biology. When Christ's life enters ours, something far deeper than behavior modification takes place. We receive a new identity at the most fundamental level. The old self that produced nothing but spiritual sickness is replaced by the life of Another flowing through us.

You are not simply a sick person trying harder to be well. You have received new blood. The life coursing through your spiritual veins belongs to Christ. That is not who you are becoming — it is who you already are.
