We're supposed to believe and confess (speak out) the thing that we're asking God for, giving us "mental assent" (mental knowledge) until we get it to the point to where we become intimate with it in our heart.
In this way, we're possessing this portion of God's Truth in our spirit and then we can move on to the next one. The Truth that we're striving for has to get from our mental realm into our spiritual realm.
The amount of revelation knowledge that a person possesses is the amount of victories in which he will walk in his life. If you don't possess very many revelation Truths of God's Word, you won't be walking in much victory. You'll be walking mostly in defeat, and this most certainly is not what God wants for you.
You must be willing to grow up in the Word ... and become more and more intimate with Jesus.
