1. The enlightenment of peoples’ secrets
2 Nothing is covered up that will not be revealed, or hidden that will not be known. 3 Therefore whatever you have said in the dark shall be heard in the light, and what you have whispered in private rooms shall be proclaimed on the housetops. Luke 12:2-3 (ESV)

13 Whoever conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy. Proverbs 28:13 (ESV)

2. The encouragement to pivot fear
4 “I tell you, my friends, do not fear those who kill the body, and after that have nothing more that they can do. 5 But I will warn you whom to fear: fear him who, after he has killed, has authority to cast into hell. Yes, I tell you, fear him! Luke 12:4-5 (ESV)

3. The estimation of our preciousness to God

32 He who did not spare his own Son but gave him up for us all, how will he not also with him graciously give us all things? Romans 8:32 (ESV)
