However, the Word of God can give you the right mindset. Romans 12:2 NLT,..."Don't copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God's will for you, which is good and pleasing and perfect."
Sickness: Meditate and confess the Word of God concerning your healing. You must not say "I am sick" That's not your name. It's just like saying "I am Emeka". Don't claim that sickness. Rather say 'I feel sick'. However, it's better to say, 'I refuse to recognize this sickness because it's not from God. The Bible says, "By His Stripes I am Healed" therefore I declare I am healed in Jesus name!' It may sound strange, the devil may even laugh at you, but pay him no attention, just continue to speak the Word into your life.
Fear: Say 'I reject fear in the name of Jesus. For God has not given me the spirit of fear, but of power, of love and of a sound mind.' 2 Timothy 1:7
Poverty: 2 Corinthians 8:9 KJV,..'For ye know the grace of our Lord Jesus Christ, that, though he was rich, yet for your sakes he became poor, that ye through his poverty might be rich.' So say, 'I refuse to be poor, I am rich in Jesus name'
I will stop here, let's leave long sermon for church:) Remember, the Word of God works only if you believe. God bless you.
