Salvation is a path of liberation or transcending the chains of ego, turning to (realization of) God and godly life
Requirements are: feeling a call/inspiration/pull/word of God written in the heart and following whatever resonates, inspires, helps, sets a good example... For me Jesus and mystic Christianity is the Morning star and main anchorage but I feel similarly also for many treasures of other religions.
Result is: a growing flow of love, awareness of God and oneness of all. I would also point out humility - not judging others, awareness of own weakness and falls, awareness of help of grace, easier to forgive (self and others), easier to move on... In short: enjoying a foretaste of heaven and full bliss in the world to come.
Consequence of failure is: I guess there is just painful prolonging. Sooner or later it catches all.
