Useless vine

Ezekiel 15:1-8
Jerusalem, a useless vine.
Son of man, how is the wood of a vine different from that of a branch from any of the trees in the forest?
As I have given the wood of the vine among the trees of the forest as fuel for the fire, so will I treat the people living in Jerusalem.
And when I set my face against them, you will know that I am the Lord. I will make the land desolate because they have been unfaithful,declares the Sovereign Lord.
Why?
Vine compare with other tree, it is useless wood. So when God against them for they are useless will be put on fire as fuel.
God has mercy to Israelite, chose them as his people, given them the way and life, but when God turn away from them. No one can escape from the judgment of the Lord.
To be a Christian should be a light in the world to shine others in the dark, or like salt to keep fresh and persistent truth among people. To be a useful Jesus follower.
How?
Let me be the light and salt in my life to affect others and reflect the love of Jesus Christ.
