Life without God does not make sense , but with God everything is possible. If you are agnostic then i'll give you argument for somebody who has ( i assume ) high expectations .
There either is God or is not . If is not then you just don't exist , but if he is then you better find out who he is and what he wants you to do.
You can either believe , and nothing happend because he is not existing or maybe something will happend after you die , why not give it a chance it does not cost you anything , because God just wants you to accept him , you can still do things you do because it's free gift .
Chances of winning lottery are so low it's not worth your money to invest into it so you ignore it , but if you found a free ticket lying somewhere on ground , wouldn't you pick it up and have " might aswell try whatever " mindset ?
What if i told you that Jesus completed at least 353 prophecy written more than thousand years before he even came to earth , if you wanted to roll dices for this chance there would not be enought atoms in the universe to roll the chances for somebody to completing all of that .
AccordingtotheScriptures.org :: 353 Prophecies Fulfilled in Jesus Christ
We live in finite universe , if we did not 2nd law of thermodynamics would say that since universe is infinite long and was forever , thus it would naturally die out of heath , because everything would have same energy and would be so away from everything that it would be cold and you could not have life .
Since there is enought energy for me to write this post , thus universe must have had beginning , beginning means that something caused it to be , because everything in this universe need cause to do something .
Only something that don't need cause to make cause for something to exist can make universe , that something is God because he never had beginning and has no end .
When you realise that , you realise you have sinned against infinite God .
If you sin against dog and kill it , you may get 2 year jail or pay fine .
If you sin against human and kill him , you will get lifetime ,death penalty or 40 years depending what country and how you did it .
If you sin against infinite God , you deserve infinite punishment .
Even if you wanted to pay your infinite punishment ( infinite debt ) , you can't , because our universe is finite , evn if you made crown out of all atoms in universe , it would be not enought .
Only God himself can pay that debt for you , he sacrifice himself for you. His name is Jesus Christ give him chance for what he has to go through for you , read 1 Cor 15:1-4 then gospel of John , did you know that Jesus resigned from some of his God power so he can feel real pain like man when he come to you? Not only he come to die for you but he also limited himself so he could feel like you.
After ressurection he got his power back , and he will judge you if you don't accept him after that all what he had to go through for you .
