The Heidelberg Catechism: Lord’s Day 48

123. Question: What is the second petition?

Answer: Thy kingdom come. That is: So rule us by Thy Word and Spirit that more and more we submit to Thee.[1] Preserve and increase Thy church.[2] Destroy the works of the devil, every power that raises itself against Thee, and every conspiracy against Thy holy Word.[3] Do all this until the fullness of Thy kingdom comes, wherein Thou shalt be all in all.[4]
