What is the gospel of Rev. 14:6-7?

What is the everlasting gospel prophesied in Revelation 14:6-7?

The soon to be revealed truth of the everlasting gospel that is now hidden from the unrighteous is, according to the apostle Paul, the same gospel that was given to Abraham when he believed God was who he said he was and was able (being the creator, director and sustainer of the universe) and willing to fulfill His promise. Because when God told him ''blessing, I will bless you'' (and through his seed all mankind) he knew God couldn't lie and not be or do what He promised to do. In other words, Abraham's (gospel) belief was counted unto him as righteousness.

This gospel is what divides the righteous from the unrighteous who try to deny or limit His sovereign unconditional love and/or power by way of their false claim of having a free will that is independent of His sovereign will and purpose..

The cross is not the everlasting gospel that saves us like most Christian religions preach, it is the 'proof' of His gospel of unconditional love and care promise that was given to all mankind...but which saves to Himself those to whom this gospel is revealed by way of the Holy Spirit freely given them.

This is this everlasting gospel that will be revealed to the 144,000 Jews who will be the first ones to be martyred at the end times in order that they become the first fruits to receive God's promise that He made to His chosen people. They won't be converted Christians (like many believe) but they will sing the song of the Lamb (the gospel) that saved them, replacing the song of Moses that couldn't.
