Here is a brief application from Romans 8 that teaches Christians do not have to be controlled by fear. Christians need not fear condemnation (verse 1).
Christians are not controlled by the flesh but by the Holy Spirit (verse 9).
Christians are not slaves to fear, but to the Holy Spirit (verse 15).
If you rely only on what is seen you will be controlled by fear (verse 24).
If you rely on what is unseen, you have hope (verse 24).
Even in your weak moments of worry and fear, the Spirit intercedes for you (verse 26).
Your deepest fears have been searched out by God and are known to him (verse 27).
The Holy Spirit, intimately aware of your fears, intercedes for you at his own initiative (verse 27).
God is in control of all the things that happen to you. You don’t have live to fear (verse 28).
