I have shared how my year of fighting breast cancer was a time that God used to purify me. He came in and burned everything up and, I mean everything, that is useless. What was worth keeping He burned for His glory. It was painful. You learn very quick how stuff doesn't matter, certain relationships don't matter and your time does not matter. It was painful but after a while it was pleasant and peaceful. Everyday, most of the day, God was my top priority. His fire cleanses us from all unrighteousness. He refines and purifies.
Just like seeing a big forest fire and all of the pretty green is gone. No flowers, no color, everything is just brown and dead. It loses all resemblance of what it once was. But after a fire when things grow back they are healthier and stronger. Maybe you feel you have been through the fire. Maybe you are in a waiting season. We are not alone. Isaiah 40: 29-31, "He gives strength to the weary and increases the power of the weak. Even youths grow tired and weary, and young men stumble and fall; but those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint."
God can rebuild us if we let Him. While we wait on His good plan we just have to trust and do good. Psalm 37: 3, "Trust in the LORD and do good; dwell in the land and enjoy safe pasture."
