In order to gain a better understanding of how worship is connected to fruitfulness, let's look at the first place we find the word "worship" in in the Bible. Gen 2:5 - Now no shrub of the field was yet in the earth, and no plant of the field had yet sprouted, for the LORD God had not sent rain upon the earth, and there was no man to cultivate the ground. In fact, our English word worship is not found there, but the idea of it is found in the original word translated as "cultivate". The original Hebrew word abad (aw-bad') means to cultivate, to till, to work, to serve, and is frequently translated as worship in the Scriptures. So, Biblically speaking, work and worship are synonymous. The idea here is that there is a connection between work and worship and, more specifically, worship is a result of fruitful work.
The original picture of worship is cultivating a field so that it brings forth it's fruitfulness. God has made creation with its fruitfulness hidden and our task, as stewards of creation, is to cultivate the field so that it yields its fruitfulness. When creation brings forth its hidden fruitfulness, it glorifies the Father, which is worship.
Jesus said it another way… John 15:8 - By this my Father is glorified, that you bear much fruit and so prove to be my disciples. Whatever our "field" is, when we work it to bring it into God's design so that it is fruitful, we are glorifying God and that is worship.
What field has God put you in to cultivate and bring it into His design?
What fruit is hidden in those places, waiting for you to bring it forth for God's glory?
Now then, you might be wondering… if worship is really about working in our God-given fields to bring forth fruitfulness, why then, when the saints gather for worship are we always singing songs? What does singing have to do with worship? When we sing songs of praise and adoration, we are singing about God's work! Christ is the ultimate worshiper. Meaning He is the One, above all others, glorifying the Father by cultivating the fields of creation and bringing forth its hidden fruitfulness. He has worked in our hearts and lives and is bringing forth fruitfulness, and that fruitfulness looks like songs of praise, adoration, celebration, and victory. When we sing, we are offering the fruit of Christ's work in our lives back to God! Ephesians. 2:10 - For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them. Therefore, worship is about doing the work of bringing God's design and order into the fields in which He has placed us so that they may be fruitful. And worship is about singing of the greater works of Jesus, the works He has done, the works He is doing, and the works that He will complete in us and throughout all of creation. As the Sovereign King, Jesus is restoring worship in the earth and songs of praise, rejoicing, adoration, celebration and victory are the fruit of His work in our field.
