For as the rain and the snow come down from heaven, and do not return there until they have watered the earth, making it bring forth and sprout, giving seed to the sower and bread to the eater, so shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and succeed in the thing for which I sent it. For you shall go out in joy, and be led back in peace; the mountains and the hills before you shall burst into song, and all the trees of the field shall clap their hands. Instead of the thorn shall come up the cypress; instead of the brier shall come up the myrtle; and it shall be to the Lord for a memorial, for an everlasting sign that shall not be cut off. (Isaiah 55:10-13, NRSV)
God’s word goes out and will not return empty. It will accomplish what God intended for it to accomplish.
Meaning, with you or in spite of you, God’s will will have the effect God was looking for.
So know that God’s word works in and through our lives and will accomplish what God needs it to and it will not return to Him empty or before it has accomplished what it needed to.
