What's the rule of thumb? Is it monthly, weekly, daily, hourly? Also, can one be a Christian and only pray once a year? Can one pray too much?
Jesus did NOT give us a schedule of praying; nor would he ever do that. This would make praying just another man-made "religion" fomented by satan.
Rather: Jesus made it plain (which MOST disobey sadly) that we were to NOT pray publicly. Matthew 6:5 And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues (includes churches) and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.
Matthew 6:6 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.
Matthew 6:7 But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking.
Later he gave us an example of HOW we should pray:
Matthew 6:9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
Matthew 6:10 Thy kingdom come, Thy will be done in earth, as it is in heaven.
Matthew 6:11 Give us this day our daily bread.
Matthew 6:12 And forgive us our debts, as we forgive our debtors.
Matthew 6:13 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.
NOTE: Under NO circumstance are we to say those "exact" words; rather use your OWN sincere words; because He sees your heart. This means, NEVER:
Write down a prayer or say it repetitiously or quote a prayer you have read, etc.
Sadly and again MOST all that pray, do this and THIS is one of the reasons that MOST prayers are never answered. The right way to do it; is to read Daniel 9 and see that God did note Daniel's prayer; because the prayer was straight from the heart of Daniel. Thus his prayer "was heard in Heaven". Daniel 9:20 And whiles I was speaking, and praying, and confessing my sin and the sin of my people Israel, and presenting my supplication before the LORD my God for the holy mountain of my God; Daniel 9:21 Yea, whiles I was speaking in prayer, even the man Gabriel, whom I had seen in the vision at the beginning, being caused to fly swiftly, touched me about the time of the evening oblation. Daniel 9:22 And he informed me, and talked with me, and said, O Daniel, I am now come forth to give thee skill and understanding.
Daniel also did something that MOST would never do; and that was to admit, in NO uncertain terms, that he and his people WERE responsible for their pain. As such, God showed mercy on him and his people and shortly thereafter, ENDED their bondage in "Babylon"; where they had suffered for 70 long years!
May Jesus richly bless you always,
