I want you to think outside the box and take a look at the Big Picture for a moment....
God has always existed. He created angels that have existed probably millions of years. Then, not too long ago, Lucifer and a third of the angels rebel for the very first time and are cast down to Earth...our planet. Then the war continues here as humanity, through our first parents, join the rebellion. God then sends His only Son to die for us so that we could be saved and live once more with Him for eternity.
I know you have heard this before, but do you realize how recent this tragedy that has happened is? How the whole universe is watching us in utter amazement to see what we will do? Whose side are we going to choose? When this is all said and done, our life's stories will be read throughout the ages. We have an awesome privilege of glorifying God in our lives here on Earth and showing the universe that God is Love.
So... when you look at the Big Picture, you won't want to waste another moment living carelessly....you will see that you have a greater purpose!
John 17:10, says that Jesus wants to be glorified in us...as He glorified His Father here on Earth.
