The issue with microevolution is the sample is extremely small, of just a small population nothing close to the size of the species. It's like saying that people who have similar ethnic characteristics are undergoing gradual evolution each time they pass on their genes. Microevolution is an analogy to evolution, but is not evolution.
But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from all sin.
