Do you have some trouble because of following Jesus? Do you have enemies that need conquering? Do you see giants on the horizon that strike you with fear? If you choose to follow God with all your heart, soul, mind, and strength, then life will not always be easy. Jesus even told us as much in John 16:33 when he said, "in this world you will have trouble."
The great news is that the verse finishes with Jesus saying, "But take heart! I have overcome the world.”
I remember these words when I read the story of the 12 spies who go into the promised land to scout out the Israelite's enemies in Numbers 13-14. Moses sends the 12 spies and when they return they all report that it is a land flowing with milk and honey that would be a great place to call home. But 10 of the spies report that there are numerous enemies including some giants that would probably defeat the Israelites should they choose to try to take the land.
But the spies Joshua and Caleb said something different. They called people to remember all that God had done while leading them out of Egypt. They called people to put their faith in a God who continually showed that He was their God and they were His people.
The people chose to live in fear and the punishment was that no adult except Joshua and Caleb ever saw the promised land. They wandered the desert for 40 years and experienced the consequence that came with their lack of faith.
We are faced with the same choice when Satan and his spiritual forces are attacking. We can cower in fear and run away to stop the attack and stay safe or we can move forward while remembering the story of God includes Him as the victor and King. Yes, it be hard. Yes, there will be times that it is scary. Yes, there will be moments when you don't see your next step clearly. This is necessary where faith is concerned. But God will give you his peace and will be with you every step you take.
Take heart, Jesus has overcome the world. The forces of darkness cannot stand against Him!
