Life in general is a battle or war. Once you are alive you are fighting a battle. There is something in your blood called the white blood cells and they protect you from disease and give you immunity. If your white blood cells have an issue it could be a problem because there are thousands of diseases that want to kill you at every point in time, and you will not be able to defend yourself. Beyond the physical battle your body fights, there is a more important battle which is the spiritual battle. Mathew 11:12 says, “And from the days of John the Baptist until now the kingdom of heaven suffers violence, and the violent take it by force.”So this is not physical violence but a spiritual battle. So there are things you can only get when you fight for them spiritually. It will be rather naive to think that all things happen by coincidence or mere chance, yes there are natural and scientific principles, however there are also spiritual principles. Ephesians 6:12 says, “For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.” In any warfare you have to know your enemy, so once you realize that your enemies are not human but spiritual beings in high places, you will be better equipped to fight. You cannot use physical weapons to fight spiritual battles. 2 Corinthians 10:4 says, “For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts.”
Now I am not saying all battles are spiritual, sometimes you may have been exposed to mosquito bites and you get malaria, the solution would be to take an anti-malaria drug and you would be fine, there may be no need for spiritual warfare. However, there are situations when the cause of sickness has no medical explanation. In such a situation, drugs and treatment can not help, but rather fasting, prayers and worship. We see this in Mark 2. A paralytic man came to Jesus for healing and He said, “son your sins are forgiven” and the man was healed, in fact, the scribes criticized Jesus that who was He to forgive sins. However, because Jesus knew the root cause of sickness was sin and not a just a disease, He forgave his sins. So sin can be the cause of your spiritual battles and once you repent in prayers you will easily overcome them. In another situation in Mark 9, a father brought is deaf and dumb son for Jesus to heal, in this case Jesus said, “You deaf and dumb spirit, I command you, come out of him and never enter him again.” And the spirit left the boy and he was healed. So the spiritual battle here was purely demonic and no drug would have solved it but only the power of God. So many battles you face in your family, work or business could be spiritual and unless you battle them spiritually you will not find a physical solution. Now like I said before, there is a balance, not each time you stumble on a stone you think that a demon wanted you to fall. However, there are cases when you have examined every physical solution and found none. Then you need to go into spiritual warfare. Very important things in spiritual warfare are fasting, worship, prayers, giving and obedience to God. You cannot fight the forces of darkness when you are living in sin or have been saved, it does not work. So whenever you solve a problem in the spirit you will see the physical solution comes automatically. May God grant you victory in Jesus name. Wish you a blessed day
