Of God, the most inescapable of all presences, the most real of all facts, the most living of all truths, the most loving of all friends, and the most divine of all values, we have the right to be the most certain of all universe experiences.  Jesus gave a great speech about security in the Jerusalem temple during Passover week of the year 27.  Mortal man assurance of Deity kinship must be faith realized. 
The reason of science is based on the observable facts of time; the faith of religion argues from the spirit program of eternity. The more of science we know, the less sure we can be; the more of religion we have, the more certain we are.  The assurance of spirit communion develops gradually. 
Spiritual assurance is the equivalent of your personal religious experience in the eternal realities of divine truth and is otherwise equal to your intelligent understanding of truth realities plus your spiritual faith and minus your honest doubts. 
Uncertainty with security is the essence of the Paradise adventure—uncertainty in time and in mind, uncertainty as to the events of the unfolding Paradise ascent; security in spirit and in eternity, security in the unqualified trust of the creature son in the divine compassion and infinite love of the Universal Father; uncertainty as an inexperienced citizen of the universe; security as an ascending son in the universe mansions of an all-powerful, all-wise, and all-loving Father.  Security in experience of cosmic citizenship. 
To recognize Deity omnipotence is to enjoy security in your experience of cosmic citizenship, to possess assurance of safety in the long journey to Paradise.  Temporal securities are vulnerable; spiritual securities are impregnable.  Temporal security is society’s prime gift to man. 
One of the characteristic peculiarities of genuine religious assurance is that, notwithstanding the absoluteness of its affirmations and the stanchness of its attitude, the spirit of its expression is so poised and tempered that it never conveys the slightest impression of self-assertion or egoistic exaltation.
