God Taught

1 Thessalonians 4:9 KJV

But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.

Gill cites three sources which teach us to care for our fellow man:

• The law of nature, "which teaches us to be kind, courteous affable and beneficent"
• The Law of Moses, "which obliges us to love their neighbors as themselves"
• The ministry of the Gospel, "which frequently inculcates the exercise of grace" 

But Paul take us beyond each of these and tells us that these believes (as is indeed true of all believers) were taught of God to love one another.

They had reason, these Christians in Thessalonica, to love one another. They were severely persecuted together. Having come to embrace the gospel of Jesus Christ they were immediately seized upon by the Jews of the area and treated in the harshest of manner. They loved one another because they needed one another. But there is still more than this implied in the passage. People who are not believers can learn to depend and love one another in this very same way and it is not because they were taught it by God. 

This is an impulse of the Spirit of God upon the Christian. 

• We love one another because we are of the same blood
• We love one another because we bear the same life within
• We love one another because we have the same home awaiting

We love one another because we are family.
