Mark 11：23 “For assuredly, I say to you, whoever says to this mountain, ‘Be removed and be cast into the sea,’ and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says.” God says that we will have whatever we say. So whatever we want to have, we can say it and have it. Unfortunately, including myself, we often say what is not God's will or say what God does not want us to have. For example, we say, “ why does he always behave like that?" "why do I see a lack of money?" like running commentary.
Whatever mountain of difficulty you have, be it a mountain of debt or serious health condition, Jesus says, “For assuredly, I say to you, whoever says to this mountain, ‘Be removed and be cast into the sea,’ and does not doubt in his heart, but believes that those things he says will be done, he will have whatever he says.” Jesus highlights the importance of saying by mentioning the word “say” three times, but the word “believe” only once. The reason why people feel "it is difficult to believe!" is because they are not saying enough of the Word with their mouths
But if we would focus more on saying God’s Word, faith will come. By saying the truth of the Word constantly, our attitude toward circumstances is going to be transformed from "sure?" to "I believe. This can not be done by our own will power but by the Holy Spirit. When we start to see the things from the viewpoint of God which is the viewpoint of victory on the cross, how wonderful to say out according to the viewpoint of God. It is matter of time to see we will have whatever we say.
