Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water. Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;) And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. - Hebrews 10:22-25 KJV

but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence; - 1 Peter 3:15 KJV

What I tell you in the darkness, speak in the light; and what you hear whispered in your ear, proclaim upon the housetops. - Matthew 10:26-28 KJV
