"Is There More Than one Gospel?...

The provided verses in Matthew 10:2; 24:13 have nothing to do with spiritual salvation since the Gospel of the Kingdom is about peace and righteousness (Hebrews 1:18, Romans 14:17), Jesus made the statement as concerning prophecy, rather than proclaiming the gospel, hence, this would not qualify for a good comparison.

Matthew 8:4 has already been explained in its parallel passage. The "for" means "because of". Matthew 23 was addressed to the Pharisees and spoke about "servanthood" v.11 and not "salvation".

Point 12:

The Gospel of the Kingdom has as its hope the second coming of
Jesus Christ back to earth to break the back of the world’s rebellion
against Christ and rescue the remnant of His chosen people Israel
after the Great Tribulation.

This would culminate in the setting up of Christ’s millennial kingdom
with the twelve apostles as judges. In the last days of God’s prophetic
program, this Gospel of the Kingdom will once again be preached in
all the world for a witness unto all nations, and then the end of the
age shall come (Dan. 2:44-45; Matt. 19:28; 24:29-31).

Rightly Divided (2 Timothy 2:15) From “Things That Differ!” (online):

The Gospel of the Grace of God has as its Hope the catching up (Rapture)
of the Church which is His Body to be taken to Its home in heaven
(1 Thes. 4:13-18; 1 Cor. 15:51-53; Phil. 3:20-21; Titus 2:13). This will
complete God’s Mystery program with the Gentiles
(Rom. 11:25; 16:25; 1 Cor. 2:7; Eph. 3:1-6; Col. 1:25-27).

Don’t let anyone tell you that there is only one gospel in the Bible. The
recognition of these two gospels in the New Testament will go a long
way toward understanding what God is doing and what He is not doing
today under Grace.

Much of the division among Christians is caused by trying to
amalgamate certain aspects of Israel’s Gospel of the Kingdom
with Truth for the Church today. Legalism, baptismal salvation,
tongues, and sign gifts have all brought confusion and disillusion-
ment to many churches and have divided true believers.

Paul’s distinctive Gospel of the Grace of God is the Divine Remedy
That brings clarity and encouragement to the saints of God.

Amen, And Amen!

Ephesians 2:8:
For ye are saved by grace, through faith; and this not of yourselves; it is God's gift:
Ephesians 2:9:
not on the principle of works, that no one might boast.

I would agree with that, and add that I see Christians today making the exact same mistake. They're waiting for Jesus to to come conquer the world in the flesh the same exact way the Jews then were. Jesus tells us His kingdom is not one you can point to and say "there it is". The popular view that Jesus is coming to set up an earthly kingdom in a fleshly way, the exact way we could point to and say "there it is" is exactly what He said it wasn't. He also likened it to a seed growing into a tree, and leaven working it's way through a huge measure of dough. These aren't very fast, not overnight kind of descriptions. He must reign until EVERY enemy is put under his feet. The meek inherit the earth not the wicked, even the whole idea of the rapture is backwards to what Jesus said would happen. Jesus said it would be like the days of Noah, right? Well in the days of Noah who was taken off the earth? Hint- it wasn't the good guys, and He told Abraham that his descendants would be numbered like the stars and sand on a shore. The kingdom of God is the spiritual kingdom we enter into when we are born again, the kingdom they all preached was "just about here", like so close you could almost/barely touch it. Just like when Jesus looked the disciples in the eyes and told them that this generation will not pass before ALL these things have taken place, and "for truly, I say to you, you will not have gone through all the towns of Israel before the Son of Man comes". There is SO much the Bible says that just does not mesh with this dispensational pre-trib view that dominates the US. It's crazy to me that this view took such a foothold so fast when #1 you have to add to His word like crazy to make it say this and #2 So much actually said contradicts the whole premise of what He said it would be.

This is the gospel? What is one to believe to be saved? The Ephesians passage is truth about the gospel, but it does not contain the gospel.
