An excellent message by John Piper on John 15:1-11. This is key for spiritual growth and sanctification and perseverance and serving the Lord in the power of the Holy Spirit. To abide in Christ means “to stay”, “to continue”, “to remain”, “to keep going”, “to dwell”, “to live in union with”. Christ is the true vine, the true source of life and power. Believers in Christ are branches, that depend on the vine. The Father is the vine-dresser or farmer. (verse 1) The Father is sovereign over the vineyard and takes away and gets rid of fake and false branches (verse 2a and verse 6), who, like Judas Ischariot, “hang out” with the other branches and pretend they are branches, but they really are not true branches. Therefore they have no life in them, and are taken away, burned in the fire (verse 6), since they bear no fruit. (see John 13:8-11 – that Judas was not “clean”, but Peter and the other disciples are already clean.)
