Jesus preached the gospel of the kingdom of God. Everywhere He went He preached the same message, “Repent for the kingdom of God,” or “the kingdom of heaven is at hand” (see Matt. 4:17, Mark 1:15). All throughout the gospels, we find that Jesus’ emphasis was on the kingdom.
The primary reason Jesus came was to inaugurate the kingdom of God. Often, we hear that the reason Jesus came was to die on the cross. Jesus did come to die on the cross, but that death on the cross was for the purpose of establishing the kingdom of God.
There were multitudes of people when Jesus preached the message of the kingdom. Some missed it—others did not.
