You ask if I can speak things into existence? Of course! So can you....You lay hands on the person that is sick and command helaing....The Word says "By Jesus stripes we WERE healed" That means its a done deal....So here's the sick guy, is he sick? Yes he is....You lay hands on him and command cancer to leave him....What HAS to happen? Well.....Cancer HAS to leave....You have the authority here, not cancer....Jesus said "Whatsoever YOU delcare legal in the Earth will be declared legal in the heavens....And whatsoever YOU declare illegal in the Earth will be declared illeglal in the heavens. You have the authority to say what is allowed....So you speak health over this sick dude and guess what? His body must line up with that...Cancer must leave.. There is an example...I have seen common ordinary Chrisians (as if there is such a thing as a common ordinary Christian) simply speak to tornadoes and the things dissipate.....I could go on....No Christian has authority that any other Christian does not have. Its not a matter of faith....We have all been given the measure of faith.
So what are the implications if I cannot do these things? Only two options, I am not a Christian or I do not have enough faith.
"He committed no sin, neither was deceit found in his mouth. When he was reviled, he did not revile in return; when he suffered, he did not threaten, but continued entrusting himself to him who judges justly. He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed. For you were straying like sheep, but have now returned to the Shepherd and Overseer of your souls." (1 Peter 2:22-25 ESV)
This verse in context is talking about sin and righteousness not physical sickness. You have to insert that into the text to get that interpretation. Same as this verse:
But he was pierced for our transgressions;
he was crushed for our iniquities;
upon him was the chastisement that brought us peace,
and with his wounds we are healed.
All we like sheep have gone astray;
we have turned—every one—to his own way;
and the LORD has laid on him
the iniquity of us all. (Isaiah 53:5-6 ESV)
Romans 12:3
For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man
the measure of faith.
Notice? It says THE measure of faith....Only one measure...We've all been given the same amount of faith! Like a seed though you have to plant it...Plant is and it WILL grow!
That is not the entire verse. Here is the entire verse with what you left off;
"For by the grace given to me I say to everyone among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith
that God has assigned. (Romans 12:3 ESV)
We do have different measures of faith. This verse also says not to think more highly of ourselves. Thinking that we can cure cancer with our faith (which is not ours at all but gods) is thinking too highly of ourselves in my opinion.
As to doing the things Jesus did and greater....Check another version of our Bible....My favorite for instance..
John 14:11-12 (CJB)
11 Trust me, that I am united with the Father, and the Father united with me. But if you can’t, then trust because of the works themselves. 12 Yes, indeed! I tell you that whoever trusts in me will also do the works I do! Indeed, he will do greater ones, because I am going to the Father.
Yes, the church has done greater things than Jesus because it is the church that Jesus gave the great commission to. He lived 33 years, the church has been preaching the gospel for almost than 2000 years.
Here Jesus is talking about works...not just things. Look! The apostles were no different from you...They put their pants on one leg at a time....just like you.....The only thing that makes them different is that they saw Jesus in the flesh...with their eyes, and you have to wait....Which is a blessing for you too.
The Apostles were different than me. Jesus gave them specific power to cast out demons (MT 10:1), Speak in tongues (Mk 16:17), and heal people (Luke 9:1-2). These were signs that they were true apostles and are not for us today as 1 Cor 12 says:
"I have been a fool! You forced me to it, for I ought to have been commended by you. For I was not at all inferior to these super-apostles, even though I am nothing. The signs of a true apostle were performed among you with utmost patience, with signs and wonders and mighty works." (2 Corinthians 12:11-12 ESV)
So....speak health into existence...Speak deliverance into existence. Speak whatever is needed into existence. and use God's Word to do it....
Yes, but I better not say bad things right or I will speak those into existence as well. This is the implication and it keeps people from really saying out loud their fears, problems, sins etc. that is necessary for real healing.
