There’s not much you can do. The Devil attacks whomever he wants, as it says in Daniel, in the latter times he’ll wear out the saints. If you’re not prepared to martial against him, or suffer for the cross, you’re not prepared to enter into the kingdom.
As it is, Christ shepherds us to the kingdom, in no way does He promise us health, wealth and happiness here on Earth, but rather, John says we will mourn upon the Earth.
Satan brings disease, death, destruction, wasting… as he’s a liar, thief and murderer. And that’s all there is to it. He destroys whom he pleases—that’s Satan—and like Job, he tries us in the furnace of affliction. If we come out purified, not as silver, but a worthy lump of precious metal, we are saved and therefore spared from the wrath to come.
I’d fear more having all the fortune, health and joy in the world, and risk going to hell, as the world rejoices in its foolishness, and squalor. Just look at the Kardashians or Tech billionaires. They spoil all love, but are happy and carefree. And the world does. It rejoices. It will rejoice, like a pig wallowing in the mud, and making sure everyone else is dirty, too. But, we being sheep, have nowhere to turn. Our fleeces aren’t being shorn, our nails aren’t being trimmed, our sores aren’t being balmmed, our wounds aren’t being cleaned, because the shepherds are spoiling the flock. And therefore, the goats have all the oats, as the shepherd doesn’t feed the one standing still, or balm their wounds, or seek after the kids of the flock, and they feed from our meat, telling us to feed them, but they don’t feed us.
So, it’s just a fact, suffer a little here, and be filled with good fruit, and though you are tormented by Satan, that’s to be expected. As this life is merely a furnace to burn away the dross.
As Jesus also says, there’s the thorns and rocks. Those who have the cares of this world, and it chokes out the riches and promise of the kingdom of God. Or those who spring up early on the rocks, and turn away due to offense and persecution. In the Early Church, but really all throughout history, except for about 200 years, the church has been persecuted. There’s been a time of rest, from about 1800 - 2000, where the saints were the greatest upon the planet, and had the riches of this life, and fed peacefully. But, sin crept in, and stole that away from the Earth, and it grows darker. So, we must be ready to die, be poor, and be meek and mild. Not to fight in wars. And if God prospers us, rejoice. For God can prosper whom He wishes. And He can restore one to full health, wealth and joy… but the LORD can also cause the fuller’s soap to wash over you, and to cleans you with lye, not for your sin, but because the world has wounded you, and has left you barren. And if you ever had soap against a wound it stings. But, that’s due to careless shepherds. Therefore, Christ is the Good Shepherd, and will shorn your fleece, and cut your nails, and balm and cleanse your wound, and feed you with the finest milk and grains. For you need Christ.
