Aren’t we grateful for our garbage truck people? They take all the nasty stuff away from our house so that we don’t have to live with it.
I wish there was a garbage truck for my mind! Oh, wait a minute! There is!
Do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus. (Philippians 4:6-7)
Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. (Romans 12:2)
If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. (1 John 1:9)
Create in me a clean heart, O God, and renew a right spirit within me. (Psalm 51:10)
Of course, just like garbage trucks, we have to willing to put the bad stuff in the bin.
