'On Earth' in the Bible

[Then] He came to His own [world, while on earth], but His own [people, the Israelites] did not welcome Him.

If I have told you about things that happen on earth and you don’t believe, how will you believe if I tell you about things of heaven?

The one who loves his life [eventually] loses it [through death], but the one who hates his life in this world [and is concerned with pleasing God] will keep it for life eternal.

Now it was before the Passover Festival [was to begin] and Jesus knew that the time had come for Him to leave this world and return to the Father. Those [living] in the world, whom He had loved, and who were His own [disciples], He continued to love [dearly] to the very end [i.e., of His life on earth].

I have glorified you on earth [by] completing the work that you have given me {to do}.
