A correct understanding of eternity can eliminate the fear of our own earthly death, and help us with the grief of of a loved one that is continuing their immortality elsewhere. A correct understanding of eternity can also help us be focussed and attentive to the value of how we spend our very short, but very meaningful time here on earth.
Jesus purposely made it very clear how we get to spend our non-earth eternity with God and with our family members that are already with Him. He said, “I am the way, the truth, and the life: no man comes to the father, but by me.” (John 14:6)
It is by accepting His death in our place, and following His will for our short time here on earth that we have certainty about our next phase of immortality.
We have many decisions to make, but this is our most important one.
The rest of our decisions and actions are our true adventure. We are already immortal, and our real quest becomes, “How does this King I serve want me to spend this part of my immortality?”
