“The gospel of the kingdom” (Matthew 4:23; 24:14; etc.) is the good news connected with, or relating to the coming kingdom. It is often erroneously said that there can be only one 'gospel'; but gospel means 'good news,' and this good news may be concerning 'Christ,' or 'the Kingdom,' or 'the grace of God.' Hence, if words are used to reveal God’s mind and thoughts, we must not confuse or join together things which He has separated.
"The Gospel (or good news) of the Kingdom" was preached when the King appeared; but after His rejection that good news is necessarily in abeyance; and, in its stead,"the Gospel (or good news) of the grace of God” is preached to sinners, both of Jews and Gentiles, until the time of the King’s second appearing shall come, when the good news of the coming King and Kingdom will be again preached.
