“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 shall succeed in the thing for which I sent it. For you shall go out in joy and be lead forth in peace; the mountains and the hills before you shall break forth into singing, and all the trees of the field shall clap their hands.”
I look at this verse as almost a prophecy to the Great Commission that Jesus would preach almost 700 years after the life of Isaiah.
Most christians take the words of Matthew 28:18-20 as our purpose and drive as christians. It’s also a very common favorite passage for most, if not all missionaries. No matter if you have done short term or long term missions, you have most likely studied and taken to heart the “go therefore and make disciples of all nations” verses and used those as your mission statement. Or something in Acts. It is always one or the other.
I love these verses and the book of Acts just as much as the next person, but the prophets of the old testament and the ‘missions statements’ they have spoken get so overlooked sometimes. These words ordained by God and spoken by Isaiah are the precursor to all of the ‘missions statements’ that we read in the new testament spoken by Jesus, Paul, or a disciple.
Verses like these in the old testament are such crucially important truths to embrace in the life of being a disciple of the Lord. The human race hasn’t been called to serve and be disciples and make disciples just from the moment that Jesus came as the example, but from the beginning of time. From the life of Isaiah in 700 BC, people, disciples, have been called to GO OUT and spread the word of the Lord. It isn’t a new thing from when Jesus came to offer salvation to the world. This mission has been the goal from when the earth was created. It is the original intention. THIS is what God wants for us and our lives.
Another aspect of these verses that bring me comfort, is knowing that amongst this mission, the Lord has a plan. He says his word will not return empty, because it will be used for the purpose of spreading the good news.
We serve a powerful God. He has a plan, and our job is to simply walk in that by faith.
