In this life we have to know our authority and operate in it. If we do not do so then Satan will be able to attack us and gain victories over us when we live below our blessings. For instance, in 2 Corinthians, Paul says this...

2 Corinthians 12:7 And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure. 8 For this thing I besought the Lord three times, that it might depart from me. 9 And he said unto me, My grace is sufficient for you: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.

Paul was strong in the Lord but he was not one of those who had lived with Jesus for three and a half years and heard his teachings as they happened and saw the context in which they were delivered. He received a lot of revelation on his own, of which we are the beneficiaries, but some things he missed out on. One of these things was the incident in Mark 11:20-24 .

Mark 11: 20 And in the morning, as they passed by, they saw the fig tree dried up from the roots. 21 And Peter calling to remembrance said unto him, Master, behold, the fig tree which you cursed is withered away. 22 And Jesus answering said unto them, "Have faith in God"!. 23 "For truly I say unto you, That whosoever shall say to this mountain, Be removed, and be cast into the sea; and shall not doubt in his heart, but shall believe that those things which he said shall come to pass; he shall have whatsoever he says. 24 Therefore I say unto you, Whatever things you desire, when you pray, believe that you receive them, and you shall have them".

With the coming of Jesus we can ask for all things which are according to God's will, in Jesus' name, and we shall have them, provided we exercise the faith of Jesus in us.

Paul didn't hear Jesus say this though and so he was carrying on with the Old Covenant prayer style where one pleaded for God to do it all. In other words instead of telling his mountain to go, in Jesus' name, he was pleading with God and asking Him to tell the mountain to go!

When he didn't work it out for himself based on Jesus' previous revelations to him, God told him directly that the grace that he had been given was enough to do what he wanted!

We have to remember this also and not get into a frazzle wondering why God hasn't done anything about our prayers, when God is waiting for us to speak to the problem ourselves and command it to get out of our way! Using Jesus' authority and name of course. We have been given the grace (empowerment) to move mountains!

We are to tell the mountain about God, not tell God about the mountain.
