To understand if God sent His Son, we will listen to the words of Jesus from John's gospel and epistle.

1 John 4:14. And we have seen and do testify that the Father sent the Son to be the Saviour of the world.
Are we listening to the words of Jesus?
It is essential we think about them.
Jesus told His disciples a number of times that He would be crucified and rise on the third day, but they did not listen. Probably they heard the words, but their minds were so occupied with Jewish teachings they did not register with their conscious thinking.
What was the problem?
Tradition had proclaimed that the Messiah would ride a donkey from the skies and in power rule in Jerusalem as king. This was so ingrained in Jewish thinking that nothing could erase it.
Tradition is very powerful and dangerous.
Thus we ask -- Did God have a Son to send?
Are we actually listening to Jesus?
