John 15:1-17
When Jesus calls us to follow Him, He is calling us to a changed life, and this process of change the Bible calls holiness (or sanctification). Because of ingrained sin and its devious influence, there is always work for the Holy Spirit to do in us in order to “conform us to the image of Christ” (Romans 8:29).
Slowly but surely, as the Spirit exposes our sin, we are to take whatever steps are necessary to kill off these sins with His help. This is a lifelong process, sometimes difficult and painful, but steadily preparing us for that day when we will be ready to spend the rest of eternity in the presence of our Holy God.
