Have you ever wondered why Elijah was not initially hesitant to lie to Ben-Hadad king of Syria? Sickness is not a sweet thing! In 2 Kings of 8:7-10..
“.. Elisha went to Damascus, and Ben-Hadad king of Syria was sick; and it was told him, saying, “The man of God has come here.” And the king said to Hazael, “Take a present in your hand, and go to meet the man of God, and inquire of the LORD by him, saying, ‘Shall I recover from this disease?’ ”
So Hazael went to meet him and took a present with him, of every good thing of Damascus, forty camel-loads; and he came and stood before him, and said, “Your son Ben-Hadad king of Syria has sent me to you, saying, ‘Shall I recover from this disease?’ ”
And Elisha said to him, “Go, say to him, ‘You shall certainly recover.’ However the LORD has shown me that he will really die.”” Sickness brings lose, sorrow, death, curse, and sickness denys and hides the truth of The Word of God!
The best and only true thing one can do to help the one who is sick is pray for them and pray with them. ” Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith will save the sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven. Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much.”
Another scenario is in 1 Kings 14:1- ” At that time Abijah the son of Jeroboam became sick.
And Jeroboam said to his wife, “Please arise, and disguise yourself, that they may not recognize you as the wife of Jeroboam, and go to Shiloh. Indeed, Ahijah the prophet is there, who told me that I would be king over this people. Also take with you ten loaves, some cakes, and a jar of honey, and go to him; he will tell you what will become of the child.” And Jeroboam’s wife did so; she arose and went to Shiloh, and came to the house of Ahijah. But Ahijah could not see, for his eyes were glazed by reason of his age. Now the LORD had said to Ahijah, “Here is the wife of Jeroboam, coming to ask you something about her son, for he is sick. Thus and thus you shall say to her; for it will be, when she comes in, that she will pretend to be another woman.” And so it was, when Ahijah heard the sound of her footsteps as she came through the door, he said, “Come in, wife of Jeroboam. Why do you pretend to be another person? For I have been sent to you with bad news. Go, tell Jeroboam, ‘Thus says the LORD God of Israel: “Because I exalted you from among the people, and made you ruler over My people Israel, and tore the kingdom away from the house of David, and gave it to you; and yet you have not been as My servant David, who kept My commandments and who followed Me with all his heart, to do only what was right in My eyes; but you have done more evil than all who were before you, for you have gone and made for yourself other gods and molded images to provoke Me to anger, and have cast Me behind your back—therefore behold! I will bring disaster on the house of Jeroboam, and will cut off from Jeroboam every male in Israel, bond and free; I will take away the remnant of the house of Jeroboam, as one takes away refuse until it is all gone.
The dogs shall eat whoever belongs to Jeroboam and dies in the city, and the birds of the air shall eat whoever dies in the field; for the LORD has spoken!” ’ Arise therefore, go to your own house. When your feet enter the city, the child shall die. And all Israel shall mourn for him and bury him, for he is the only one of Jeroboam who shall come to the grave, because in him there is found something good toward the LORD God of Israel in the house of Jeroboam.. “
Sickness is not something you can wish for someone not even to your own enemy.
