Oswald Chambers said this quote

“ I want to tell you a growing conviction with me, and that is that as we obey the leadings of the Spirit of God, we enable God to answer the prayers of other people. I mean that our lives, my life, is the answer to someone’s prayer, prayed perhaps centuries ago.It is more and more impossible to me to have programmes and plans because God alone has the plan, and our plans are only apt to hinder Him, and make it necessary for Him to break them up. I have the unspeakable knowledge that my life is the answer to prayers, and that God is blessing me and making me a blessing entirely of His sovereign grace and nothing to do with my merits, saving as I am bold enough to trust His leading and not the dictates of my own wisdom and common sense. ”
