God says that it will just like He will bless your sermon or Sunday School Lesson. Do you believe that? Do you believe he will bless when you go door to door, bus visitation, hospital visitation, prison ministry, or any other kind of ministry? If he blesses his word going out, then why would He not bless the word going out as a voice broadcast to thousands of people as has never been done since the creation of the world? Is it the voice broadcast system which only calls those you program it to call and only gives the message that you record responsible, or is God also responsible for the word that goes out on a voice recorded message. People record radio and T.V messages and God blesses them so why would He bless radio and T.V. and not voice broadcasting? No! I can firmly say that God will bless any means that we can use to reach the lost. –
Isaiah 55:11 – So shall my word be that goeth forth out of my mouth: it shall not return unto me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it.
What else does God say about reaching the lost? Luke 14:21-23 So that servant came, and shewed his lord these things. Then the master of the house being angry said to his servant, Go out quickly into the streets and lanes of the city, and bring in hither the poor, and the maimed, and the halt, and the blind. (22) And the servant said, Lord, it is done as thou hast commanded, and yet there is room. (23) And the lord said unto the servant, Go out into the highways and hedges, and compel them to come in, that my house may be filled.
