“In hope of eternal life, which God, that cannot lie, promised before the world began;”  
Titus 1:2

God, that cannot lie, made a promise before the world began; if he did so at that time, that means he made the world to fulfill that promise; the purpose of the existence of the world today is the acceptance of that promise!
Is it possible that every inhabitant on the earth is a Jesus loving, spirit filled Christian? Yes, that was the promise before the world began!
Now that the world is in existence, he has given that promise, he sent Jesus so the world could have that promise:
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”  John 3:16
It is now a possession available for every man to receive once he hears the gospel.
“And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.”  2 Corinthians 6:18
It was God’s idea to have children just like him, and it his passion to have many, that’s why he enlists every one of his child on the earth to participate in enlarging his family.
Think about it, this God that can do anything and is greater than all, finally has something that he really wants and you can give him! Do so with all your heart and might, tell people about his glorious promise and give it to them- it’s free!
