Fight the Good fight
Notice the Apostle Paul tells Timothy to FIGHT! I've never considered myself a great fighter but I've had more than my share and I am aware of the mechanics of fighting.
When we were kids and someone was going to have a fight we would all gather to watch. Some of the fights were just too one sided and it wasn't really a fight. It was really just a beating. Today we call that a bully taking advantage of someone weaker than they are. A real fight is back and forth, trading blows.
But the fight Paul is talking about is the fight of faith. The keeping of one's faith is similar to a physical fight. If you want to be a Christian I can promise you that this life will fight you for it. It's going to hit you hard, and like the Rocky movie, nobody hits harder than life. Remember how Rocky lost it all? The world tries to take your joy and your peace with every unwanted circumstance, every unexpected tragedy, and every unforeseen pitfall. Being a Christian is not for sissies!
So what do you do? Let me give you three options. You can do what so many Christians do and curl up in the fetal position, cover your face and just take it. I want to be truthful with you and say there are times when that's the only thing you can do. Some hardships are simply tests of endurance.
Then there are those Christians who help the enemy by inflicting wounds on themselves. That's when you just agree with every negative thought that comes in: "I'm not good enough, not smart enough, etc." Your opponent doesn't have to do anything then. You will beat yourself up.
Then there's the third option: you can fight. You fight by remembering God's promise that no weapon formed against you will succeed at taking you down (Isaiah 54:17). You hide His words in your heart and wear them out on your sleeve. You stand up against the lies that seek to sink your ship.
And it's going to be rough. You will definitely get hit and wounded. Some of the punches you take will leave you dazed. Always remember, the enemy doesn't fight fair, and he's very aware of your weak points. Don't think for a moment that he won't sucker punch you right where it hurts.
I read where one of those extreme cage fighters said that he didn't want to die with no scars. The greatest fight to ever take place was at Calvary. Praise God, Jesus won that battle but He also came away with scars. He showed them to the disciples after His resurrection (Luke 24:39). In fact, His scars were proof that He had died and came back to life. I think our scars bare the same resemblance. They are the evidence that we are overcomers. They qualify us to speak to those in pain and say, "I've been there."
So, if you're in a battle, fight and keep your head up. You may lose a few battles, but remember that you've already won the war. God Bless!
