1 Cor 15:1-6
The testimony of two confirms the fact of the one true gospel!
The one true gospel is the only message preached to unbeliever and believer alike in the grace of God. The one true gospel is the Mashiach died for our sins according to the Tanach (Old Testament), He was buried and He rose again the third day according to the Tanach. Yeshua of Nazareth is the Mashiach of God. As the one true gospel is preached to the unbeliever, God wills His grace for the person to accept the one true gospel or God does not will and they reject. There is no free will, only God’s will. There is no “evidence that demands a verdict”, but only grace according to the will of God that causes a person to accept the one true gospel in its entirety. When God does give grace to a person it is as the wind, which we know not where it comes from, and where it goes. But God knows where the Spirit came from and where it will go. For it is His Spirit. When God brings forth His grace it is brought forth from above and the person is born from above.
And the gospel preached to the believer is the same gospel, for there is only one gospel. There will be the understanding of Yeshua ha Mashiach in the preaching of the one true gospel to the children of grace. In the midst of the preaching of the one true gospel spiritual understanding will come forth: that is, understanding of Yeshua. The saints will know their God and His love, and God will be their teacher.
