Read Daily Courage, from Day by Day with the Persecuted Church, compiled by Jan Pit at One Place.
"Prayer has been well named the breath of the soul. If the breath is cut off you automatically die - this also applies to the spiritual life. Daniel had already fought with the lions when there was no lion to be seen. The roaring lion crept up on Daniel in his private room - not in the lions den. When Daniel was thrown to the visible lions he had already wrestled with the invisible lion and... won. Therefore the visible lions in the den were unable to do anything to Daniel, for there was no more ‘flesh' on him. Do we see the tactic of Satan - he who goes round as a roaring lion, seeking whom he may devour? The contact with God must always be there. Praying Christians are a danger to the powers of darkness. God is seeking such pray-ers."
...your Father knows what you need before you ask Him. "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.']
