Hi, I would say that salvation is deeply rooted into faith, in fact faith is to believe something even when you cannot see of understand it, Hebrews 11:1. The total essence of salvation is mind over matter in which we can be as power as we want to be. When Jesus told people it is best to develop faith that could move mountains that kind of belief is awesome, Matthew 17:20.
On the other hand, salvation is founded on our faith in God turned inwards. As it was spoken by Jesus Christ faith as strong as that would make nothing impossible for you. In acquiring the right elements in our minds to heal, this powerful faith in ourselves is much necessary and a motivator in accomplishing salvation.
John 4:14
Modern English Version (MEV)
14 but whoever drinks of the water that I shall give him will never thirst. Indeed, the water that I shall give him will become in him a well of water springing up into eternal life.”
