Greetings! https://youtu.be/uduSAFL-DmE?si=Qez_-qCMWZSTkMDV There's only one thing that our death teaches and that thing is judgement which will take place after our deaths. This judgment is something that cannot be escaped by anybody and this is because it's inevitable as death is inevitable.
Having said this, it's only one being that cannot die and this being is God Almighty who is the father of all. In the book of Matthew 6:9-13 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done on earth, as it is in heaven. Give us this day our daily bread. And forgive us our debts, as we forgive our debtors. And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, forever. Amen.
In the above scriptural verse, Jesus Christ is making reference to the father, God Almighty who is the only being referred to in 1 Timothy 6:16 Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.
So, the above scriptural verse is in sync to Matthew 6:9-13 and it's only telling us about who the being that cannot die and that immortal being is God.
In conclusion and according to the Bro. Eli's teaching, in the book of Hebrews 9:27 And as it is appointed unto men once to die, but after this the judgement.
This above scripture is a testament that it's been appointed by God for man to die once for the purpose of judgement.
Thanks for reading.
