Original sin (Adam’s first disobedience) imputed guilt and a sin nature to all humanity, separating us from God at birth. Dr. Bryan Stensaas explains imputation (Adam’s guilt placed on us), inheritance (sin nature passed down), and why every person is born on Satan’s side, lost and condemned. Using a simple diagram (God’s side vs. Satan’s side), he shows the cross as the only bridge back through faith in Christ’s blood.
