The God of Mercy has provided a way for you to not go to hell at great cost to Himself. There are no little sins, any deviation from God's perfect law is damnation. Even just once.
There is only one mortal sin in the world - not accepting Christ and His free offer of Salvation dearly bought for you.
I HAVE accepted Jesus.
Its a lot of that narrow and arcane theology that turns me off.
I still sin.A lot less than I used to but the Devil does get into me once in a while.I admit that.I forgive myself and try to do better the next day.
