Thought from Today’s Old Testament Passage:
First Samuel 18:10 says that an evil spirit from God came on King Saul. How can this be explained if only good comes from God?
It is not quite accurate to say that only good comes from God. While it is true that God’s original creation was good and that God Himself is not tempted by evil, nor does He tempt (in the sense of attracting or enticing) any man to evil, nevertheless it remains true that genuine goodness in a moral God requires that a real difference be made between good and evil. As the ordainer and preserver of the moral order, it is absolutely necessary for God to punish sin, no matter how much love and compassion He may feel toward the sinner…
Insofar as God has established the spiritual laws of cause and effect, it is accurate to say that Saul’s disobedience cut him off from the guidance and communion of the Holy Spirit that he had formerly enjoyed and left him a prey to a malign spirit of depression and intense jealousy that drove him increasingly to irrational paranoia. Although he was doubtless acting as an agent of Satan, Saul’s evil bent was by the permission and plan of God. We must realize that in the last analysis all penal consequences for sin come from God, as the Author of the moral law and the one who always does what is right (Gen. 18:25).
