GOD’s existence is SELF-EVIDENT even though not materially detectable

Self-evident does not mean God should make Himself detectable as unbelievers have been expecting from long back. His existence can be even MORE SELF-EVIDENT than the situation where HE tries personally to convince everyone through some material means.

Situation is similar to someone who admits he has ego, it is SELF-EVIDENT truth but
it is even MORE SELF-EVIDENT if his actions reveal existence of ego in him such as he gets angry with servants but is always soft and sweet towards his superiors even under extreme provocation.

Apply this principle in the case of God and Soul, they would become SELF-EVIDENT.
