Years ago I received the following Word from a visiting Evangelist:
Isaiah 41:15-16; "Behold, I will make you into a new threshing sledge with sharp teeth; you shall thresh the mountains and beat them small, and make the hills like chaff. You shall winnow them, the wind shall carry them away, and the whirlwind shall scatter them; you shall rejoice in the Lord, and glory in the Holy One of Israel."
He began to explain that "you shall thresh the mountains and beat them small" referred to the effect of the preaching to bring down the mountains of impossibilities.
He continued to explain that "the whirlwind" was a reference to the ministry and the work of the Holy Spirit.
Since this time I have prayed and contended for the power of the Holy Spirit in declaring and demonstrating Jesus Christ to any and all that would listen. God is faithfully fulfilling His word for His glory.
