Matthew 10:16 (KJV)
Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.

We have been chosen by Our Lord and Our God and called to do the work of Him who has sent us. Even while we were in our mothers womb Our Lord and Our God appointed us and set us apart and placed us Upon This Rock Of Jesus Christ so that we may bring His lost souls back to Him and help them to be in a position to regain eternal life through Jesus Christ who is Our Lord and  Our Savior.
