Jesus taught his disciples to pray:
Matthew 6:5-14 And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward. 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. 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. 8 Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him. 9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name. 10 Thy kingdom come. Thy will be done in earth, as it is in heaven. 11 Give us this day our daily bread. 12 And forgive us our debts, as we forgive our debtors. 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. 14 For if ye forgive men their trespasses, your heavenly Father will also forgive you: 15 But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
Luke 11:1-4 And it came to pass, that, as he was praying in a certain place, when he ceased, one of his disciples said unto him, Lord, teach us to pray, as John also taught his disciples. 2 And he said unto them, When ye pray, say, Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done, as in heaven, so in earth. 3 Give us day by day our daily bread. 4 And forgive us our sins; for we also forgive every one that is indebted to us. And lead us not into temptation; but deliver us from evil.
This provides a pattern of prayer.
We are to pray in secret.
We are not to use vain repetition.
We are to praise God.
We are to pray for God’s kingdom to come on earth.
We are to pray for our daily food.
We are to pray for the forgiveness of sins
We are to pray for deliverance from evil.
We are to give thanks to God in prayer.
1 Thessalonians 5:18 In every thing give thanks: for this is the will of God in Christ Jesus concerning you.
We are to pray for others.
James 5:16 Confess your faults one to another, and pray one for another, that ye may be healed.
We are to pray for our enemies.
Matthew 5:44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
We are to pray for those in authority.
1 Timothy 2:1-4 I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men; 2 For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty. 3 For this is good and acceptable in the sight of God our Saviour; 4 Who will have all men to be saved, and to come unto the knowledge of the truth.
We are not to neglect prayer.
Luke 18:1 And he spake a parable unto them to this end, that men ought always to pray, and not to faint;
Elijah is cited to demonstrate that the ‘effectual fervent prayer of a righteous man availeth much’.
James 5:16-18 The effectual fervent prayer of a righteous man availeth much. 17 Elias was a man subject to like passions as we are, and he prayed earnestly that it might not rain: and it rained not on the earth by the space of three years and six months. 18 And he prayed again, and the heaven gave rain, and the earth brought forth her fruit.
Prayer is to be made to the Father through Jesus.
Ephesians 2:18 For through him we both have access by one Spirit unto the Father.
Colossians 3:17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
Hebrews 7:25 Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.
1 John 2:1 My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
