John 3:16 For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.
This is the most important verse from the Bible because it is like a deal between God and Jesus that was so intents and meaningful it means that we can live in heaven without having to sacrifice anything except believing. We should never forget that is what true Christianity is all about.
Oh utanity, you are a legend! LLOL!
Despite the mistaken view that this verse is more important than any other, every verse is important. Some have more substance than others this is true. But generally speaking we don't talk about one verse being more important than others. Some are certainly more significant and perhaps that is what you are saying. I am pleased to see that you are endeavoring to understand the bible somewhat.
Believing is not a sacrifice. Believing is in this sense in John 3:16 talking about trust. It is where you put belief into action. In other words, if there is no action, there is no belief. Belief is not a mere head nod or some kind of assent. To put your trust in Jesus means to stop putting trust in yourself. It is the reversal of the Garden of Eden. There Adam put his trust in himself and not in God. He thought he could eat the fruit and become like God. In doing so, he stopped trusting in God. This was as I have said before an act of Treason. It would the same as you building your own police in force in South Australia and to stop trusting the South Australia Police and premier.
For God so loved the world that he gave his only son. so that whosoever trust in him - puts into action his loyalty to Jesus - will not remain trusting himself and reap the implications of that - but will instead be reconciled back to God, ready to be loyal to him in all that he does. This is the Christmas Story. Loyalty to the King of Heaven.
