"The word is near thee, in thy mouth and in thy heart:
that is, the word of faith, which we preach:
that if thou shalt confess with thy mouth Jesus as Lord,
and shalt believe in thine heart
that God has raised him from among the dead,
thou shalt be saved."
"Go into all the world,
and preach the glad tidings to all the creation."
Jesus (Mark 16:15)
"Beloved, believe not every spirit,
but prove the spirits, if they are of God;
because many false prophets are gone out into the world."
1 John 4:1
