Paul’s life was an ongoing struggle, i.e. before he met with Christ, until His death. He pleaded with churches to follow Christ’s example, he argued with his fellow apostles, he suffered natural disasters.

Scripture teaches that we are to fight evil with good. (1 Peter 3:9, Romans 12:17). We are also reminded that through the blood of Jesus, we have been rescued from the slavery of our sin and there is no returning to that bondage.
Also be aware that the Devil holds some power in our world, and he is to be resisted (1 Peter 5:8-9). In all these, we were encouraged by Jesus’ words. “In the world you will have tribulation; but be of good cheer, I have overcome the world” (John 16:33).

If you are facing battle in some area of your life right now, keep fighting. Everyone experiences life as a battle at some point in time. Paul also told us how he fought for his life when talking about some of his trials.
He concluded that he had “fought a good fight” (2 Timothy 4:17). Our Lord Jesus also encouraged us with the same word when He said, “Strive [or fight] to enter by the narrow door; for many, I tell you, will seek to enter and will not be able” (Luke 13:24).
