116. Why is prayer necessary for Christians?
Because it is the chief part of thankfulness which God requires of us,1 and because God will give His grace and Holy Spirit only to those who earnestly and without ceasing ask them of Him, and render thanks unto Him for them.2
 Ps. 50:14–15.  Matt. 7:7–8; Lk. 11:9–10, 13; Matt. 13:12; *Eph. 6:18.
117. What belongs to such prayer which is acceptable to God and which He will hear?
First, that with our whole heart1 we call only upon the one true God, who has revealed Himself to us in His Word,2 for all that He has commanded us to ask of Him;3 second, that we thoroughly know our need and misery,4 so as to humble ourselves in the presence of His divine majesty;5 third, that we be firmly assured6 that notwithstanding our unworthiness, He will, for the sake of Christ our Lord, certainly hear our prayer,7 as He has promised us in His Word.8
 Jn. 4:22–24.  Rom. 8:26; 1 Jn. 5:14.  Ps. 27:8.  2 Chron. 20:12.  Ps. 2:10; 34:18; Isa. 66:2.  Rom. 10:14; Jas. 1:6.  Jn. 14:13–16; Dan. 9:17–18.  Matt. 7:8; Ps. 143:1; *Lk. 18:13.
118. What has God commanded us to ask of Him?
All things necessary for soul and body,1 which Christ our Lord comprised in the prayer which He Himself taught us.
 Jas. 1:17. Matt. 6:33. *1 Pet. 5:7. *Phil. 4:6.
Praying the lord's Prayer
119. What is the Lord’s Prayer?
Our Father 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 forgive our debtors. And do not lead us into temptation, but deliver us from the evil one. For Yours is the kingdom and the power and the glory forever. Amen.1
 Matt. 6:9–13; Lk. 11:2–4.
"Our Father Who art heaven,"
120. Why did Christ command us to address God thus: “Our Father”?
To awaken in us at the very beginning of our prayer that childlike reverence for and trust in God, which are to be the ground of our prayer, namely, that God has become our Father through Christ, and will much less deny us what we ask of Him in faith than our parents refuse us earthly things.1
 Matt. 7:9–11; Lk. 11:11–13; *1 Pet. 1:17; *Isa. 63:16.
121. Why is it added, “in heaven”?
That we might have no earthly thought of the heavenly majesty of God,1 and from His almighty power expect all things necessary for body and soul.2
 Jer. 23:23–24; Acts 17:24–25, 27.  Rom. 10:12; *1 Kgs. 8:28; *Ps. 115:3.
"Hallowed be Thy name."
122. What is the first petition?
“Hallowed be Your name;” that is, grant us, first, rightly to know You,1 and to sanctify, magnify, and praise You in all Your works, in which Your power, goodness, justice, mercy, and truth shine forth;2 and further, that we so order our whole life, our thoughts, words, and deeds, that Your Name may not be blasphemed, but honored and praised on our account.3
 Jn. 17:3; Matt. 16:17; Jas. 1:5; Ps. 119:105.  Ps. 119:137; Rom. 11:33–36.  Ps. 71:8; *Ps. 100:3–4; *Ps. 92:1–2; *Eph. 1:16–17; *Ps. 71:16.
"Thy Kingdom Come."
123. What is the second petition?
“Your kingdom come;” that is, so govern us by Your Word and Spirit, that we submit ourselves to You always more and more;1 preserve and increase Your Church;2 destroy the works of the devil, every power that exalts itself against You, and all wicked devices formed against Your Holy Word,3 until the fullness of Your kingdom come,4 wherein You shall be all in all.5
 Ps. 119:5; 143:10.  Ps. 51:18; 122:6–7.  1 Jn. 3:8; Rom. 16:20.  Rev. 22:17, 20; Rom. 8:22–23.  1 Cor. 15:28; *Ps. 102:12–13; *Heb. 12:28; *Rev. 11:15; *1 Cor. 15:24.
"Thy will be done on earth as it is in heaven."
124. What is the third petition?
“Your will be done on earth, as it is in heaven;” that is, grant that we and all men renounce our own will,1 and without disputing obey Your will, which alone is good;2 so that every one may fulfill his office and calling as willingly and faithfully3 as the angels do in heaven.4
 Matt. 16:24.  Lk. 22:42; Tit. 2:12.  1 Cor. 7:24.  Ps. 103:20–21; *Rom. 12:2; *Heb. 13:21.
"Give us this day our daily bread."
125. What is the fourth petition?
“Give us this day our daily bread;” that is, be pleased to provide for all our bodily need,1 so that we may thereby acknowledge that You are the only fountain of all good,2 and that without Your blessing neither our care and labor, nor Your gifts, can profit us;3 that we may therefore withdraw our trust from all creatures and place it in You alone.4
 Ps. 104:27–28; 145:15–16; Matt. 6:25–26.  Acts 14:17; 17:27–28.  1 Cor. 15:58; Deut. 8:3; Ps. 37:3–7, 16–17.  Ps. 55:22; 62:10; *Ps. 127:1–2; *Jer. 17:5, 7; *Ps. 146:2–3.
"Forgive us our debts, as we forgive our debtors."
126. What is the fifth petition?
“And forgive us our debts, as we forgive our debtors;” that is, be pleased, for the sake of Christ’s blood, not to impute to us miserable sinners our manifold transgressions, nor the evil which always clings to us;1 as we also find this witness of Your grace in us, that it is our full purpose heartily to forgive our neighbor.2
 Ps. 51:1–4; 143:2; 1 Jn. 2:1–2.  Matt. 6:14–15; Ps. 51:5–7; *Eph. 1:7.
"And do not lead us into temptation,
but deliver us from the evil one."
127. What is the sixth petition?
“And do not lead us into temptation, but deliver us from the evil one;” that is, since we are so weak in ourselves that we cannot stand a moment,1 and besides, our deadly enemies, the devil,2 the world,3 and our own flesh,4 assail us without ceasing, be pleased to preserve and strengthen us by the power of Your Holy Spirit, that we may make firm stand against them and not be overcome in this spiritual warfare,5 until finally complete victory is ours.6
 Jn. 15:5; Ps. 103:14–16.  1 Pet. 5:8–9; Eph. 6:12–13.  Jn. 15:19.  Rom. 7:23; Gal. 5:17.  Matt. 26:41; Mk. 13:33.  1 Thess. 3:13; 5:23–24; *2 Cor. 12:7.
"For Thine is the kingdom and the power and the glory forever. Amen."
128. How do you close this prayer?
“For Yours is the kingdom, and the power, and the glory, for ever;” that is, all this we ask of You, because as our King, having power over all things, You are willing and able to give us all good;1 and that thereby not we, but Your holy name may be glorified for ever.2
 Rom. 10:11–12; 2 Pet. 2:9.  Jn. 14:13; Ps. 115:1.
129. What is the meaning of the word “Amen”?
“Amen” means: so shall it truly and surely be. For my prayer is much more certainly heard of God than I feel in my heart that I desire these things of Him.1
 2 Cor. 1:20; 2 Tim. 2:13; *Ps. 145:18–19.
