How do you Christians choose to believe in God without the concept of hell altering your decision making.
If it is a factor when deciding where to put your faith, doesn't this mean your only choosing God to save your own neck's.
If not, how?
You are starting from the wrong foundation.
Subconsciously you are starting from the foundation that we are all essentially good people, and have to remain good to avoid going to hell. And if we sin then God sends us to hell. And that's why we need a saviour to pay the penalty. Many Christians still will think in this way.
The truth of the matter is this. When you are born, you are born into corruption already through the fallen nature of Adam.
Nobody deserves to go to heaven. For all have sinned and fallen short of the glory of God. Then God,
because He loves you, came to Earth, born of a virgin (not into the corruption of Adam), and went to the cross without sin. He paid the price of a sinner, yet was totally innocent. He loved you so much that He paid the penalty
so that you would not have to.
Hell exists (and has to exist) because God is a righteous judge. Every transgression will be settled in the great accounting of mankind. God is perfect. He is also fair. Nobody ends up in hell who doesn't deserve to be there. But God made a way though His Son, that if you are willing to receive Him, believe Him, call upon His Name, repent of your sins and follow Him - then you have a narrow gate through which you can avoid this place called Hell.
Unfortunately people think the gate is wide. It's not. It's narrow. There is only one door. And He is Jesus Christ.
Do not be arrogant to think there are many doors, many ways --- for this is how the world thinks.
