The whole meaning of prayer is that it is about the will of God for the Christian. It was not meant to change the holy nature of God but to change the Christian daily in fellowship. When it is prayer, it is always going first with praising God, confessing one's sins, thanking God and asking for one's needs so that God will be glorified.
1 John 5:14-15 says, "And this is the confidence that we have in him, that, if we ask any thing according to His will, He heareth us: and if we know that He hear us, whatsoever we ask, we know that we have the petitions that we desired of him." This shows that Christian prayer has never been about selfish desires but it has always been "Thy will be done on Earth as it is in Heaven."
What about you? Is your prayer really asking for God's will or are you as of right now too focused on your will?
