In our lives we are going to go through plenty of battles. Just because we get deeper into our walks with God it doesn't mean the battles quit coming. John 16:33 "I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world." God calls us to have peace during these battles. You can easily see if you have peace during these times by how many people you talk to about it(phone calls, emails, not being able to keep your mind off the problem). When we have peace we spend that time with God. I'm not saying it's not great to have people you can talk to but it's even better when you spend that time with God.
An example I like to use when thinking about peace is imagine you are in a small wooden row boat on a river. At times the river is quiet and we can just drift along checking on occasion how the boat is doing and just making sure it's going in the right direction. Life is calm and we are just enjoying the ride. We have seasons of life where it is like this. Everything is going our way and we can recover from previous battles and just be thankful it's over. Then the rapids hit and the boat rocks and forth, we have to be careful of rocks jutting up out of the water, flipping the boat over or springing a leak in the boat. How do we handle that? Are you able to keep that peace that was there when the boat was drifting or are you so flustered you can hardly think straight?
Psalm 139:23 Search me, God, and know my heart; test me and know my anxious thoughts. God will test you. If you ask for things in your life like opportunities to serve, to move up in a job or to minister more He will try your heart. I often think of it like this have you ever seen when someone put glass into a fire and shapes it into a lamp, or a pot? The heat changes the shape of the glass and the final result is something very beautiful. God will do that to us. It's under the heat and pressure that He can really shape us. How do you react when things don't go your way? What do you do when the furnace breaks and you don't have the money? What is your reaction when someone talks badly about you and tells lies? He is watching you. He wants to know that He can trust you so He can use you.
So when the battles come please keep your eyes on God and read His word, pray and I hope it helps you to remember the examples given above. You aren't alone in battles and you won't outgrow them. God is there and He's watching you too as they happen.
