“For as the rain comes down, and the snow from heaven, and do not return there, but water the earth, and make it bring forth and bud, that it may give seed to the sower and bread to the eater, so shall My word be that goes forth from my mouth; it shall not return to Me void; but it shall accomplish what I please, and it shall prosper in the thing for which I sent it.” Isaiah 55:10-11 NKJV

Here’s a truth by which your spirit can be buoyed…
God’s word will never return unto Him void.

It will accomplish what He has sovereignly decreed.
So see that your own words, with His words, stay fully agreed.

Don’t be double minded, thereby tossed like a wave of the sea.
Stay with God, in agreement, causing things that “be not”…to “be.”

P. A. Oltrogge

“Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all, (As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were. Who against hope believed in hope, that he might become the father of many nations, according to that which was spoken, so shall thy seed be.” Romans 4:16-18 KJV

“Now faith is the substance of things hoped for, the evidence of things not seen.”

“And Jesus answering saith unto them, ‘Have faith in God. For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass, he shall have whatsoever he saith. Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.’” Mark 11:22-24 KJV
