In one sense, with every ministry there is a building process that takes place. You look at examples in scripture of the construction of the tabernacle, the temple, or even the walls of Jerusalem; there was a lot of work involved. Within any ministry it is important that the foundation be solid. The greatest foundation that any ministry can build on is Jesus Christ. He is the solid rock, He is the chief cornerstone. As you build your ministry upon Jesus, this assures stability. One of the tools that we use to build with is the Word of God. When a church is being taught the Word of God it brings the church to a place of maturity in their walk with the Lord. Along with the Word of God, you have the work of the Spirit of God. When the Spirit of God is actively at work in the church, the evidence is the fruit of the Spirit, which is love.
Another application that one can make from this verse is how not to build. There are tools that can be used in the building of a ministry that may prove to be damaging in the long term. For example building on a powerful persona of a gifted communicator. Building on the premise of an impressive building. Constructing through various methods that may bring a crowd, but do not build a healthy church. It is possible to labor, and actually be laboring in vain. Whatever we are building for the kingdom of God, be it our marriage, our church, or our own personal lives, we want to do it Gods way and for His glory. Remember, the flesh profits nothing. As long as we remain open to the Lords leading, and His direction we can have confidence that we are not laboring in vain. The Bible tells us, "it is not by might, nor by power, but by His Spirit". Keep your hands to the plow, and don't look back!
