Romans 10:13-15

13 "Everyone who calls, 'Help, God!' gets help."
14 But how can people call for help if they don't know who to trust? And how can they know who to trust if they haven't heard of the One who can be trusted? And how can they hear if nobody tells them?
15 And how is anyone going to tell them, unless someone is sent to do it? That's why Scripture exclaims, A sight to take your breath away! Grand processions of people telling all the good things of God!
