To whet your appetite, here are some good definitions of prayer I've come across in preparing to teach:
Prayer is a sincere, affectionate pouring out of the heart or soul to God, through Christ, in the strength and assistance of the Holy Spirit, for such things as God has promised, or according to his Word, for the good of the church, with submission in faith to the will of God. (John Bunyan, Praying in the Spirit)
Prayer is more than just an expression of emotion. It is finding the way to God and speaking with Him, whether the heart is full or empty. (Dietrich Bonhoeffer, Psalms: The Prayer Book of the Bible)
Prayer is God's appointed means for appropriating the blessings that are ours in Christ Jesus. (D. A. Carson, A Call to Spiritual Reformation)
Pray, then, in this way:
"Our Father who is in heaven,
Hallowed be Your name.
Your kingdom come.
Your will be done,
On earth as it is in heaven.
Give us this day our daily bread.
And forgive us our debts, as we also have forgiven our debtors.
And do not lead us into temptation, but deliver us from evil. For Yours is the kingdom and the power and the glory forever. Amen."
