Another verse came to mind, as I was reading this article: https://activechristianity.org/7-extraordinary-promises-for-those-who-overcome All 7 Promises, and 7 verses, are Amazing, and directly from Our Lord Jesus Christ in Revelation, but Promise 4 is clearest imho.
"The 4th extraordinary promise: Power over the nations, a rod of iron, and the morning star
“And he who overcomes and keeps My works until the end, to him I will give power over the nations – ‘He shall rule them with a rod of iron; They shall be dashed to pieces like the potter’s vessels’ – as I also have received from my Father; and I will give him the morning star.” Revelation 2:26-28.
So, to receive these Promises, the Lord Himself says that we are to "keep His Works until the end", which seems to me to be very clear.
God Bless.
