Jdg 4:6 KJV - And she sent and called Barak the son of Abinoam out of Kedeshnaphtali, and said unto him, Hath not the LORD God of Israel commanded, [saying], Go and draw toward mount Tabor, and take with thee ten thousand men of the children of Naphtali and of the children of Zebulun?
Jdg 4:7 KJV - And I will draw unto thee to the river Kishon Sisera, the captain of Jabin's army, with his chariots and his multitude; and I will deliver him into thine hand.
Jdg 4:13 KJV - And Sisera gathered together all his chariots, [even] nine hundred chariots of iron, and all the people that [were] with him, from Harosheth of the Gentiles unto the river of Kishon.
Jdg 4:14 KJV - And Deborah said unto Barak, Up; for this [is] the day in which the LORD hath delivered Sisera into thine hand: is not the LORD gone out before thee? So Barak went down from mount Tabor, and ten thousand men after him.
Jdg 4:15 KJV - And the LORD discomfited Sisera, and all [his] chariots, and all [his] host, with the edge of the sword before Barak; so that Sisera lighted down off [his] chariot, and fled away on his feet.
Jdg 4:16 KJV - But Barak pursued after the chariots, and after the host, unto Harosheth of the Gentiles: and all the host of Sisera fell upon the edge of the sword; [and] there was not a man left.
I think Sisera would say he engaged his enemy of his own free will. What say you?
Act 9:1 KJV - And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest,
Act 9:2 KJV - And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.
Act 9:3 KJV - And as he journeyed, he came near Damascus: and suddenly there shined round about him a light from heaven:
Act 9:4 KJV - And he fell to the earth, and heard a voice saying unto him, Saul, Saul, why persecutest thou me?
Act 9:5 KJV - And he said, Who art thou, Lord? And the Lord said, I am Jesus whom thou persecutest: [it is] hard for thee to kick against the pricks.
Act 9:6 KJV - And he trembling and astonished said, Lord, what wilt thou have me to do? And the Lord [said] unto him, Arise, and go into the city, and it shall be told thee what thou must do.
Saul's will (free? or Satan's will) was to continue persecuting Christians. Did Saul fall to the earth of his own free will? If so, why? Why did Saul submit his will to the Lord's will? Why didn't Saul remind the Lord of his free will?
