Mark 16:15-18 (Last words Jesus said in Mark)
And He said to them, “Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned. And these SIGNS WILL follow those WHO BELIEVE: In My name they WILL cast out demons; they WILL speak with new tongues; they WILL take up serpents; and if they drink anything deadly, it WILL by no means hurt them; they WILL lay hands on the sick, and they WILL recover.”
But GO rather to the lost sheep of the house of Israel. And as you go, preach, saying, The kingdom of heaven is at hand.’ Heal the sick, cleanse the lepers, raise the dead, cast out demons. Freely you have received, freely give.
Luke 10:8-9 (Sending the 70 people)
Whatever city you enter, and they receive you, eat such things as are set before you. And HEAL THE SICK THERE, and say to them, The kingdom of God has come near to you.’
Luke 10:17-20 (70 Come back with Joy)
Then the seventy returned with joy, saying, “Lord, even the demons are subject to us in Your name.”
And He said to them, “I saw Satan fall like lightning from heaven. Behold, I GIVE YOU THE AUTHORITY to trample on serpents and scorpions, and over all the power of the enemy, and nothing shall by any means hurt you. Nevertheless do not rejoice in this, that the spirits are subject to you, but rather rejoice because your names are written in heaven.”
Most assuredly, I say to you, he who BELIEVES in Me, the works that I do HE WILL DO ALSO; and GREATER WORKS than these he will do, because I go to My Father. And WHATEVER you ask in My name, that I will do, that the Father may be glorified in the Son. If you ask anything in My name, I WILL do it.
Then Peter said, “Silver and gold I do not have, but what I do have I give you: In the name of Jesus Christ of Nazareth, rise up and walk.” And he took him by the right hand and lifted him up, and IMMEDIATELY his feet and ankle bones received strength.
Now, Lord, look on their threats, and grant to Your servants that with all BOLDNESS they may speak Your word, by stretching out Your hand to heal, and that SIGNS AND WONDERS may be done through the name of Your holy Servant Jesus.”
Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. And THE PRAYER OF FAITH WILL SAVE THE SICK, and the Lord WILL raise him up. And if he has committed sins, he will be forgiven. Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, FERVENT PRAYER OF A RIGHTEOUS MAN AVAILS MUCH.
