If Jesus Christ were the only way to heaven then you wont find anyone there who got there more than 2000 years ago. I believe that being good and honest and basically obedient to the Nine Commandments you will be at peace at the end of your life. If there is heaven after that I doubt that even Jesus himself would turn you away.
NINE commandments?
Yikes
You are deluded. The Scriptures, breathed out by the Holy Spirit, confirm it to the MAX. Like everyone else you have a choice, and currently you are choosing The Lie (pretending you are “as God”, knowing good and evil when you know nothing). You can choose to listen to God via Scripture (primarily Paul the apostle) and get an attitude adjustment or you can test out your theory and face certain doom.
Jesus is the Way and every other way is not the Way.
"And this is His commandment: that we should believe on the name of His Son Jesus Christ and love one another, as He gave us commandment." 1 John 3:23
Then why did Jesus die on the cross?
Your statement here makes me think you are part of the OTHER half.
