All you need is to believe without any doubt in the truth that Jesus' name is powerful enough to do anything and you will have it. I testify 100% in Jesus because He is the only way.

I don't care who doesn't believe me as long as they believe this because it is 100% true.

If you don't have the faith in His name then you won't receive. To get rid of unbelief, do a fast because unbelief will prevent you from receiving. Or doubt. Or listening to people say "nah, you won't get it." Ignore that and rebuke Satan and kill him with the Word "It is written" ask and you shall receive and I believe in the name of Jesus it is mine. Do it.
