Isaiah 55:10-11 NKJV
 "For as the rain comes down, and the snow from heaven, And do not return there, But water the earth, And make it bring forth and bud, That it may give seed to the sower And bread to the eater,  So shall My word be that goes forth from My mouth; It shall not return to Me void, But it shall accomplish what I please, And it shall prosper in the thing for which I sent it.
Whenever the natural water from heaven contacts the earth it causes fruit to come forth. That fruit benefits those with needs as well as those who assist in meeting needs. The rain does not stop before it hits the ground. It does not return to its source unproductive. It accomplishes its mission. It is the same with spiritual rain. When the Word and the Spirit contact the heart of a man, it causes fruit to come forth. That fruit benefits the man who needs it and the person who assists in meeting needs. The needy eats the fruit and the sower gets the seed to produce more fruit. Spiritual water does not return to its Source unproductive. It accomplishes what God wants it to. It prospers in the place He sent it. He sends the rain with a purpose. When that purpose is fulfilled He is pleased. The condition of the ground the water hits determines the level of success. The Word will undoubtedly produce somewhere. It cannot return to God as a useless thing. Since He sends it to do a work, the work will be done. When we make our spirits good ground - receptive to the Spirit and the Word, we will be the ones to experience the productivity God intended. We must be receptive with an attitude that God will work in us as He pleases, not as we please. We may open up to the word expecting one thing that we want done, but that may not be the reason God sent that word to us. So let us be open to not only receiving the Word but to receiving God's pleasure as the Word comes forth.
The earth cannot be productive by itself. It must have water added to make it productive. Likewise, if we do not receive the ministry of the Spirit and the Word, we remain dry unproductive dirt. We must remember that when we find ourselves trying to bring forth fruit without the ministry of the Holy Spirit and the anointed Word. Also, just like you cannot always see the water working, we must continue to receive the Word even though we cannot always see it working. We walk by faith, knowing that eventually we will see the results.
