John 4: 16 – 18: Jesus saith unto her, Go, call thy husband, and come hither. The woman answered and said, I have no husband. Jesus said unto her, Thou hast well said, I have no husband: For thou hast had five husbands; and he whom thou now hast is not thy husband: in that saidst thou truly.
Jesus discerned that the woman of Samaria already had five husbands, and could see that she was presently living with a sixth man because her sin was not yet repented of nor was it under the blood, and was therefore not forgiven nor forgotten by God. Upon this basis the Father was able to reveal these things to Jesus, because the woman’s sinful past and present adulterous state was still connected to her.
The prophet again demonstrated the Messianic sign of discernment in these last days (Hebrews 4: 12), and there were many people who stood before him with unconfessed sin in their lives. The prophet was able to call out this sin by vision because it had not been repented of and was therefore not forgiven by God nor erased from His memory.
But then there were occasions during the discernment lines where people with unconfessed sin in their lives repented in their hearts to God of the evil they had done, and when they stood in the presence of the Angel of the LORD next to the prophet, their past sin was not seen in a vision nor was it called out, because God had forgiven them, and what they had done was now under the blood and erased from His thinking. The wonderful power of true confession and genuine repentance is made beautifully plain in 1 John 1: 9: If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
