There will always be sadness in a physical world. Only in the spiritual world will there be no more sadness, for those who are close to God.
I do not know why you keep saying that, as if I am going to believe it. I never will.
Jesus was teaching salvation by works, and then Paul changed that teaching to salvation by grace.
That was Baha'u'llah.
How many times do I have to post the same verses?
John 14:19 Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also.
John 17:4 I have glorified thee on the earth: I have finished the work which thou gavest me to do.
John 17:11 And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are.
The context of those verses was not about there being or not being second coming of Jesus. One could say that they weren't referring to Jesus not returning because Jesus wasn't going to return, but that's adding an assumption into the text. The conclusion you get from the text is that the context isn't about the return of Jesus or the idea that people were teaching a false doctrine about the return of Jesus.
Why would there be sadness in a physical world with no death? Paul and Thomas saw the risen Jesus, and Revelation 1:9 and 1:20 Jesus is described as appearing in glorified form.
Jesus didn't teach salvation works. No one is good but God alone means that we are sinners who cannot be saved by good works.
