"Analyze your environment. 'Conduct spiritual housecleaning, if necessary, and do not let evil enter your presence.' Your mind will clear, temptation will lift, and you will dwell in God's safety, protection, healing, blessings and favor."
"Finally, my friends, keep your minds on whatever is true, pure, holy, friendly, and proper. Don't stop thinking about what is truly worthwhile and worthy of praise." (Phil. 4:8)
