Jesus defines the unforgivable sin —blasphemy against the Holy Spirit — as accusing Him of being possessed by the devil (Mk 3:22). In Luke's Gospel, He refers to blasphemy against the Spirit as refusing to acknowledge Him publicly (Lk 12:9-12). In both cases, those sinning know the truth but intentionally pervert or conceal it. Blasphemy against the Spirit may be intentional denial of the truth either vocally or silently. This sin is unforgivable because those sinning by denying the truth would refuse to admit the sin and thereby never ask for forgiveness. Some of the religious leaders of Jesus' time knew Jesus was innocent but they did not oppose those plotting to kill Him (Jn 8:45).

Abortionists know the fetuses they abort are human beings but pretend this is questionable. Some reporters intentionally slant their stories or even lie outright. In war time, countries often manipulate data to justify destroying their enemies. Many business people know that the products they produce or market are not good for people but rationalize their sin and do it anyway. If we are lying to ourselves in any area of our lives, we may be walking into the territory of the unforgivable. We may be dangerously close to crossing a line after which we will never repent. We must be true to Jesus, the Truth (Jn 14:6).
