You will keep him in perfect peace, whose mind is stayed on you: because he trusts in you. Isaiah 26:3
Praise God! It is very important to guard our mind and to have the mind of Christ. Satan tries to attack the mind and thought life but resist him standing firm in the faith and he will flee from you. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Ephesians 6:12 When Satan tries to attack your mind with negative, fearful and unwanted thoughts, speak God’s Word which is the two-edged sword and do not let your mind to be idle or wandering off but let your mind and heart always be filled with God’s Word. Do not let sin control your mind but let the Spirit control your mind so that there will be life and peace that is in Christ Jesus.
When you let the false thought given by Satan to grow in your mind then fear starts to fill your heart and you lose your peace. But you can overcome this by God’s grace, don’t give heed or admit to Satan’s thoughts but just focus on God and bring every thought into the captivity of Christ! Put on the full armor of God so you will be able to resist the enemy in the time of evil and stand firm. Do not let fear grip your heart, trust and have faith in God. God is always with us even to the end of the age and He will strengthen us. For God has not given us the spirit of fear; but of power, and of love, and of a sound mind. 2 Timothy 1:7
When the cares and burdens of this world fills your heart, you just focus on the problems but fail to look upon God and cast everything on Him, He is the only one who can deliver and bring you out of those. Peace I leave with you; my peace I give you. I do not give to you as the world gives. Do not let your hearts be troubled and do not be afraid. John 14:27 Due to the worldly worries and anxieties some people often become sick but don’t worry about anything; instead, pray about everything. Ask God what you need and thank him for all He has done. When you believe and have faith in God, He will deliver you from your sickness, He is our loving Father and He cares for us. A heart at peace gives life to the body.
