Sing, O barren, thou that didst not bear; break forth into singing, and cry aloud, thou that didst not travail with child: for more are the children of the desolate than the children of the married wife, saith the LORD. Isaiah 54:1"
The Lord God Almighty is a wonder, and His wisdom is unsearchable. He has given the barren in His kingdom the utmost opportunity to be fruitful. He said the barren need not cry, complain, or become bitter and discouraged.
It is time for them to sing unto the Lord Jesus Christ; it is time for them to sing spontaneously and cry aloud in prayer. He said that their children are many and full of wonders, and that is why they are going through that period of barrenness. It is just a period of testing; it will pass away.
This principle was applied by Rebekah, Hannah, and Elizabeth, and they gave birth to mighty men of valor. Dear beloved, if it seems you are barren, don't be worried; instead, continually sing and cry aloud unto God, and you will see your miracle.
Hallelujah!
