"What I tell you in darkness, that speak ye in light: and what ye hear in the ear, that preach ye upon the housetops.. And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
Are not two sparrows sold for a farthing? and one of them shall not fall on the ground without your Father. But the very hairs of your head are all numbered.
Fear ye not therefore, ye are of more value than many sparrows (Matthew 10:27-31)
Follow God's Instruction
Do what God has told you to do. Say what God has told you to say. "For it is not you who speaks, but the Spirit of your Father which speaks in you (Matthew 10:20). Don't be afraid of what man thinks about it. God is the One Who will Judge every mans work according to His Gospel; Jesus Christ (Romans 2:16). Seek to please God. Nothing happens without His infinite knowledge. God takes care of the sparrow and He will certainly take care of you. "Fear you not therefore, you are of more value than many sparrows (Matthew 10:31). While in prayer, listen to God's Holy Spirit; He will reveal to you what you need to speak about in public. "Whosoever therefore shall confess Me before men, him will I confess also before My Father which is in Heaven (Matthew 10:32).
