If there is to be Revival in Your Heart, then you must set aside a time of quiet Prayer to God. Prayer is a means of intentionally conveying a message to God. You may say God already knows what I need–He is God. True; but prayer is for us. A moment to be alone with God and He being our only focus. This must be more than just a whispered "God help me" which has it’s time and place; but we need to set aside a time each day to be alone with God. Christ himself went out early in the morning to be alone with the Father. So what did Christ have to say about prayer?
Matthew 6: 5 And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.
6 But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly.
7 But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking.
8 Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him.
9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
10 Thy kingdom come, Thy will be done in earth, as it is in heaven.
11 Give us this day our daily bread.
12 And forgive us our debts, as we forgive our debtors.
13 And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, for ever. Amen.
Prayer must come from the heart. It is a means of communicating to God our desires, our hopes, and more importantly our loving devotion to Him. So you may still say, "What do I say?" That is the beautiful part–just get alone, intent on being near to God. The Holy Spirit within you will intercede for you.
Romans 8: 22 For we know that the whole creation groaneth and travaileth in pain together until now.
23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
24 For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?
25 But if we hope for that we see not, then do we with patience wait for it.
26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
27 And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
