Until satan and his demons are bound up and cast into the lake of fire, there will always be some conflict or another caused by sin and pride residing in our hearts. We can come closer, by giving our hearts and lives to Jesus, and letting His Spirit guide us into all peace and truth, but there will always be human nature to plague us till the end of time.
"You will hear of wars and rumors of wars, but see to it that you are not alarmed. These things must happen, but the end is still to come. Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. All these are the beginning of birth pains... And this gospel of the Kingdom will be preached in all the world as a testimony to all nations, and then the end will come... At that time the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man coming on the clouds of heaven, with power and great glory. And He will send out His angels with a loud trumpet call, and they will gather His elect from the four winds, from one end of the heavens to the other (Matthew 24: 6-8, 14, 30-31 BSB)."
