For if thou shalt knowledge with thy mouth that Iesus is the Lord, and shalt believe with thine heart that God raised him up from death, thou shalt be safe.
Let therefore abide in you that same which ye heard from the beginning. If that which ye heard from the beginning shall remain in you, ye also shall continue in the son, and in the father.
And this is the victory that overcometh the world, even our faith. Who is it that overcometh the world: but he which believeth that Iesus is the son of God?
