Who hath heard such a thing? who hath seen such things? Shall the earth be made to bring forth in one day? or shall a nation be born at once? for as soon as Zion travailed, she brought forth her children. – Isaiah 66:8

God’s works are not tied by time. The more spiritual a force is the less it lies within the chains of time. The electric current, which has a greater nearness to the spiritual than the grosser forms of materialism, is inconceivably rapid from that very reason, and by it time is all but annihilated. The influences of the Spirit of God are a force most spiritual, and more quick than any thing beneath the sun. As soon as we agonize in soul the Holy Spirit can, if He pleases, convert the person for whom we have pleaded. While we are yet speaking He hears, and before we call He answers… With God’s Spirit our present instrumentalities will suffice to win the world to Jesus; without Him, ten thousand times as much apparent force would be only so much weakness. The spread of truth, moreover, is not reckonable by time…The Spirit of God is able to operate upon the minds of men instantaneously…Oh for the travail that would produce immediate results.

So, in answer to prayer, God not only bestows speedy blessings, but great blessings. There were fervent prayers in that upper room “before the day of Pentecost had fully come,” and what a great answer it was when, after Peter’s sermon, some three thousand were ready to confess their faith in Christ, and to be baptized. Shall we never see such things again? Is the Spirit straitened? Has His arm waxed short? Nay, verily, but we clog and hinder Him. He cannot do any mighty work here because of our unbelief; and, if our unbelief were cast out, and if prayer went up to God with eagerness, and vehemence, and importunity, then would a blessing descend so copious as to amaze us all.~ C.H. Spurgeon
