Worship Lessons From Isaiah

Hey everyone!

We are excited to continue with this month’s series on worship from the Old Testament. We are also excited to introduce Johnny Sierra to you! Johnny is a worship leader for Rethink Life Church in Orlando, Florida. We love Johnny's heart for making biblical worship known to all. We know you are going to enjoy this post from him!

Before we get started today, please click the links below to get caught up in the current series:


As we continue with Worship Lessons from the Old Testament, we will dive into the book of Isaiah. Let's start with a biography of this prophet. Who exactly was Isaiah?

  • Born In Jerusalem
  • Lived about 700 years before Christ
  • Jewish tradition says he was of royal descent and may have been a cousin of King Uzziah
  • He was married to a prophetess (Isaiah 8:3) and had two sons
  • His ministry lasted at least 40 years
  • Quoted the New Testament more than any other prophet, and the list can go on and on...(but I will spare you from boredom)


To answer that question, let’s look at what the definition of worship is. Worship means to honor with extravagant love and extreme submission (Webster's Dictionary, 1828). Within the modern church, King David is often looked at as one of the main worshipers in the Old Testament. One of the key ways King David sought to worship God was through music. Now, music is an incredible form of worship, but it is certainly NOT the only form of worship. We cannot overlook the fact that worship is a lifestyle...It isn't something you merely do but something you live out. To go a little further in depth, let me break down a certain event in Isaiah's life that I think really showcases him and what true worship really is all about.

Isaiah's Call

The prophet Isaiah is considered to be one of the greatest prophets to have ever lived. His leadership was one of deep conviction and boldness. He spoke of current and future things that many people of his time did not understand. I believe that as great as Isaiah's ministry was, nothing would have taken place, if it was not for one particular turning point in his life:

Then I said, It’s all over! I am doomed, for I am a sinful man. I have filthy lips, and I live among a people with filthy lips. Yet I have seen the King, the Lord of Heaven’s Armies. Then one of the seraphim flew to me with a burning coal he had taken from the altar with a pair of tongs. He touched my lips with it and said, See, this coal has touched your lips. Now your guilt is removed, and your sins are forgiven.” - Isaiah 6:5-7

The Prophet Isaiah received a vision of God — of His power, His majesty, and His purifying holiness. He caught sight of God's majesty which led him to brokenness, with a humble view of himself and his culture. As Isaiah experienced, just a glimpse of who God is drives away our inflated self-importance and the insufficiency of our physical talents in worship. But it also can give us a new perspective of what is truly valuable in this life. It changes the way we live and the way we worship. When we understand who God is and where we stand in correlation to Him, we come out different people, leaders, and worshipers.

Have you ever heard the saying, "Actions speak louder than words"?

The Bible puts great detail to Isaiah's response (action) to God's call, which I believe was a pivotal moment in the start of Isaiah's ministry.

Then I heard the Lord asking, “Whom should I send as a messenger to this people? Who will go for us?” I said, “Here I am. Send me.” - Isaiah 6:8

God's call is never an easy one, but for Isaiah, everything began the moment that he responded "Here I am." True worship is a daily response to God, which is shown through our faith, obedience and love. It is the starting point of the work that God will do with you and through you. As leaders of worship teams, churches, ministries, etc., we have to respond to God's call every day because we cannot lead others where we have never been. 

If Isaiah was to lead others into repentance and holy living before the Lord, then he would first have to be cleansed and forgiven of his sins. 

If God has placed you as a worship leader, pastor, or in any kind of leadership role, then realize that as great as that position may be, it will require more from you. It will require ALL OF YOU! It will require you to fully lead by example and take the path less traveled. It will require you to truly experience the presence of God. It will require you to go where no one else may be going, and it will require you to do what no one else may be doing. 


Isaiah’s ultimate calling and purpose was to serve as God’s ambassador to the people of Judah and proclaim their sinful status in God’s eyes. He served as God's hands and feet, and for that, we can look at Isaiah's life as a life of true worship.

My challenge to you is to begin your time of prayer saying, "Here I am."  In saying that, you are letting God know that you are available, that you are all His, and that His agenda and plans are what ultimately matter most to you. Once you say those words, take some time to really listen. Let Him speak deeply into you. Let Him direct your agenda, meetings, worship preparation, message, etc. Allow God to continue His work in you, so that He can accomplish His will and purpose through you. We are His hands and feet, so let our lives be a complete reflection of Him because that is a life of true worship. 

God Bless You,
Johnny Sierra
