For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live. For as many as are led by the Spirit of God, these are sons of God. For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, “Abba, Father.” 

– Apostle Paul, Romans 8:13–15 (NKJV)

For God has not given us a spirit of fear, but of power and of love and of a sound mind. Therefore do not be ashamed of the testimony of our Lord, nor of me His prisoner, but share with me in the sufferings for the gospel according to the power of God,  who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was given to us in Christ Jesus before time began, but has now been revealed by the appearing of our Savior Jesus Christ, who has abolished death and brought life and immortality to light through the gospel, 

– Apostle Paul, 2 Tim 1:7–10 (NKJV)

For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes… For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness…

– Apostle Paul, Romans 1:16;18 (NKJV)
