1) In what way is faith not self-deception?
2) Is a person who has faith in a God that you do not believe in, say for example Siva, practicing a form of self-deception?
I believe I can answer both of those with one answer. But first, a question: Is it self-delusion to come to a conclusion that is based on observed evidence, no matter how popular or unpopular that conclusion may be? Some insist on defining faith as "belief without proof", if that is the case, then we all have faith, depending on how you define "proof".
American Heritage Dictionary:
1. The evidence or argument that compels the mind to accept an assertion as true.
If one defines proof as such, then we all have faith.
Faith is defined in the Bible as "Now faith is the assurance of things hoped for, the proving of things not seen."- Hebrews 11:1
I believe that faith is based on the things seen, things learned, things reasoned upon. That faith in the unseen is not blind. While God is not seen, we believers have faith that He exists, because we observe His creation’s complexity and design, that is proof . Non-believers and believers also come to conclusions about the unseen.
Because none of us knows for a certainty, but rather believes that (to varying degrees) our conclusions are correct, it can be stated that we all have varying degrees of faith. It is the object of that faith that differentiates the "believer" from the "non-believer". Do we ultimately put our faith in men, or God?
Are we all "practicing self-deception", then?
Time will tell who are deceiving themselves and who are not, as the facts are proven or disproved.
