The Heidelberg Catechism, This Lord's Day week 52

Q127: What is the sixth petition?
A127: And lead us not into temptation, but deliver us from evil; 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 Thy 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]

Q128: How do you close this prayer?
A128: For Thine is the kingdom, and the power, and the glory, forever; that is, all this we ask of Thee, because as our King, having power over all things, Thou art willing and able to give us all good;[1] and that thereby not we, but Thy holy name may be glorified forever.[2]

Q129: What is the meaning of the word Amen?
A129: 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]

Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, Unto him be glory in the church by Christ Jesus throughout all ages, world without end. Amen.[1]
