In the kingdom of God, there are different levels of spirituality. There are some people who are mature and others not yet. There are children of God who have decided to live and walk only in the divine health. God wanted that His children live in the same nature as His, He is our example and we must fix our eyes on Jesus, the author and the finisher of our faith.
Indeed, Colossians 1:12-13 says: “giving thanks to the Father who has qualified us to be partakers of the inheritance of the saints in the light, He has delivered us from the power of darkness and conveyed us into the kingdom of the Son of His love.” We have been delivered from the kingdom of darkness which can indeed has nothing to do against us for we are in the light.
In Christ, there are realities of darkness which cannot affect us. Ephesians 4:30 says: “and do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption.” We have been sealed by the Holy Spirit so that nothing from outside be able to affect us. There’s power which protect me from all things. 1 Peter 5:8 says that the devil prowls about us like a roaring lion to find who to devour. But he can’t for there is the wall of the Holy Spirit which protects us.
In this world, there are those who flee from the devil and others that the devil flees from them. Get to know then that you have such a power, as Christian (the anointed of God), which can make the craftiness of the devil flees from you; this is why, for being able to defeat the devil for always, you have to be aware of that power walking in us.
To conclude, believe that you can live your whole life without having any form of sickness. Mathew 16: 18: “ and I also say unto to you that you are Peter , and on this rock I will built My church, and the gates of Hade shall not prevail against it.” this verse is the evidence that we can live easily, without fear because Jesus took charge of everything during His death and resurrection.
