As the rain and the snow come down from heaven, and do not return to it without watering the earth and making it bud and flourish, so that it yields seed for the sower and bread for the eater,
so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it.
God the Father sent His Word into the Earth to accomplish an appointed task. The task of completing the process of the resurrection. Jesus was not tasked with dying alone. He was tasked with following all the way through to resurrection and ascension back to the Father.
Our tasks are similar in nature. We are not simply tasked with putting things to death that should die. We should be living a life that is full of resurrection and bringing things back to God as offerings which please Him.
It is like the parable of the talents. It is not satisfactory to bury what we have and present back to the Lord exactly what He gave us. We are to produce more with the talents we already have. Then we can present something to Him from the fruits of our labor.
Jesus accomplished that which He was sent for. He took His offering to the mercy seat and covered it for us. He brought something back to the Father that was not there before. He asks no less from us.
