The Second Coming of Jesus Christ is one of the great truths of Scripture. In our passage, Jesus mentions it for the first time in the gospel of Matthew.
The goodness and generosity of our God is amazing! He not only wants to give us salvation, but also reward us for faithfully serving Him. This is merely "a taste" of the enormous feast of biblical teaching on the doctrine of rewards for the Christian.
Jesus always hits the bull’s-eye! In this passage He expects us to do the right thing with the right heart attitude. Jesus hates hypocrisy!
