That tells me that you believe in different gospels about a different Jesus. Its the same gospel and same Jesus as there is only One Gospel and One Christ/Lord. Jesus did not give Paul a different gospel than He did His other disciples.Yes. The gospel preached prior to His resurrection is the gospel of the kingdom, i.e. the message that the earthly kingdom of God is near and that people needed to prepare themselves to be worthy to enter it (Mark 1:14-15). After His resurrection, Paul describes the gospel as being the death, burial, and resurrection of Christ for our sins (1 Cor. 15:1-8). These details could not have been known beforehand except through divine revelation, as Jesus did not proclaim them openly (and His disciples didn't even understand what He was saying when He told them about it privately). In fact, the gospel that Paul preached could not have been revealed beforehand since he says the rulers of this age would not have crucified Jesus if they had known about it (1 Cor. 2:8).
There is One God
There is One Lord
There is One Faith
There is One Baptism
There is One Jesus
There is only One way to God
There is One Savior
There is only One Church
There is only One body of Christ
And there is One Gospel
6 I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
9 As we said before, so say I now again, if any man preach any other gospel unto you than that ye have received, let him be accursed.
So since there is only One God, One Savior, One way to God through Christ, One faith, One baptism and One Gospel- there is only one way to be saved.
Paul defines that Gospel by which we are saved below:
1 Corinthians 15:1-19
Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, 2 by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain.
3 For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He was raised on the third day according to the Scriptures, 5 and that He appeared to Cephas, then to the twelve. 6 After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep; 7 then He appeared to James, then to all the apostles; 8 and last of all, as to one untimely born, He appeared to me also. 9 For I am the least of the apostles, and not fit to be called an apostle, because I persecuted the church of God. 10 But by the grace of God I am what I am, and His grace toward me did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me. 11 Whether then it was I or they, so we preach and so you believed.
12 Now if Christ is preached, that He has been raised from the dead, how do some among you say that there is no resurrection of the dead? 13 But if there is no resurrection of the dead, not even Christ has been raised; 14 and if Christ has not been raised, then our preaching is vain, your faith also is vain. 15 Moreover we are even found to be false witnesses of God, because we testified against God that He raised Christ, whom He did not raise, if in fact the dead are not raised. 16 For if the dead are not raised, not even Christ has been raised; 17 and if Christ has not been raised, your faith is worthless; you are still in your sins. 18 Then those also who have fallen asleep in Christ have perished. 19 If we have hoped in Christ in this life only, we are of all men most to be pitied.
Only One way to be saved, by One Person, One Gospel and One Faith. In Him alone. Scripture is really very exclusive here but inclusive to all that come to Him freely!
Then I saw another angel flying overhead, with the eternal gospel to proclaim to those who dwell on the earth—to every nation and tribe and tongue and people
And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved
1 Timothy 2:5
For there is one God and one mediator between God and men, the man Christ Jesus,
Jesus passed on the gospel to His Disciples. Its the same Gospel but Christ had not suffered, died, risen yet.
hope this helps !!!
