Don’t you consider it amazing how some believers can recite the Lord's prayer daily and still tolerate situations and circumstances that are not in alignment with the will of God in heaven? Don’t claim to be holy when your experiences are incongruent with the will of God for His children.
Prayer is a primary means by which we change whatsoever is not the will of God on the earth right now to reflect and realign with the will of God in heaven. There is a heavenly standard in the presence of God concerning every area of our lives as we are living on the earth. In heaven, there's a blueprint and prayer is a means of making every area of your life agree with the blueprint in heaven. 
For example, God’s will for students is to succeed very well and be above (Deut. 28:10). Therefore, if your experience is contrary, employ the principles of prayer in your studies and examination preparations until it is like God's will in heaven. You don’t have to go to heaven to know God’s will because His will is given to us in the Bible. Whatever you see in the Bible is the will of God and that is exactly what God wants in heaven. Study the Bible and in the place of prayer, reverse anything in your life that does not line up with the Bible picture. That is what it means to pray “Your will be done.” It is a prayer of power, authority and warfare. 
PRAYER: Lord, let your will be done in every area of my life: my family, my career, my studies, my finances and everything I put my hands to in Jesus’ name. Amen!
