“You will keep in perfect peace those whose minds are steadfast, because they trust in you” Isaiah 26:3 NIV).
Never dwell on your fear, your illness, your worry. Dwell on God's faithfulness. Think more of Him, and less of what you face in this life. He is the Great Physician, your healer. Dwell on that. He is your strength. Dwell on that. He is your rock no matter what comes against you. Dwell on that. He is your power to overcome adversity. Dwell on that. He is all you need at any moment. Dwell on that.
Even His most faithful children often do not claim healing for every part of their lives. Claim healing of your body, of your mind, and of your spirit. Love Him continually, and focus on Him always. Where your mind focuses, your heart follows. Allow Him to be what you can't be. Allow Him to handle what you can't handle. And then no weapon that comes against you will harm you.You will know perfect peace no matter what.
“Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things” (Philippians 4:8, KJV). Now dwell on that.
