Human mind is like a container which has the left and right lobes called mind and cardia. All knowledge or contents from what we see, read or hear, pass through the mind and when they are understood it is transferred to the cardia lobe. In Greek this is called 'gnosis and epignosis.'
The senses and organs of human especially the brain, blood, ear and eyes play very important role in the human's personality or soul. The personality compartments are mentality which thinks, reasons and chooses. The emotion feels or is the appreciator, receptor or anxiety part . The conscience is developed during maturity process and likewise self-consciousness. This is the part wherein a person may want to change part of his physical aspect yet he/she knows that he/she is still that man or woman. The functions of body and soul are conduits.
The body is the access to the world. The home, school, government and culture try to prepare all humans to be able to be well informed and well adjusted to live in the complex world. The soul or personality is the access to self, to the real needs and developing character . The human spirit is the access to God to know Him that man needs a greater power apart from himself. All humankind are born with faith like faith in work, faith in parents, faith in education, faith in self and others. However the only faith that results to eternal salvation is faith in the only Saviour of mankind, Jesus Christ the Lord. His Gospel or good news requires every human to believe in Him, that He died on the cross and nailed Adam's sin (every child is born with), was buried and then resurrected. When a person reaches this decision faith, God performs His promise, He saved to the uttermost the believing soul or person. The Holy spirit quickens the human spirit and he/she can now be taught and eat spiritual food which is the word of God.
Choosing is vital and necessary for our eternity. While the family and the race we belong, we can never choose here on earth, our present, our future and destiny need our choice. We can rather choose to have a strong tie and close relationships to whom we were born rather than blame anyone. The world weighs us down and even prod upon us. God on the other hand respects every freedom of choice. This is God's agape love character. He waits until we understand His grace and choosing Him and the Gospel is a conduit when He performs His act of saving. The work is completely finished on His cross, man just needs to agree with that. Believing His Gospel needs man's choosing for His eternal salvation. Studying the Scriptures for everyday spiritual growth, learning, understanding, believing and applying needs a moment by moment choosing. This is the handbook or instruction manual for the living saved souls/persons. This is the beginning of spiritual life.
Unbelief is the only sin that will separate man from God for eternity. In theology this is called spiritual death even though the body and soul live and move. Choosing for his/her eternal abode is only until he/she lives in the physical realm. All sins have been dealt with at His cross but God's forgiveness and salvation is only operational to a person that has faith and the only object is Jesus Christ. The presence of plants, trees, fish, animals, planets and seasons are some of the witnesses of God that He lives. He wants a personal intimate relationship with humans and the only way is when he/she personally acknowledges that Jesus Christ is God who became flesh, died on the cross to pay all penalty of all humankind sin, was buried and rose again. He/she needs Him for salvation.
The character of a person improves depending upon what he/ she feeds his/her mentality. What influences are accepted and believed. If he/she puts on the truth of God's word, He/she become truthful, peaceful and stable. His/her emotions become happier and conscience is strengthened with the truth. There is acceptance of self. The power that drives any person depends upon the things that he/she believes. On the other hand if he continues to believe the lies of the devil, to superstitions and conform to the standard of the world and selfish ways, he/she continues to be confused, fearful and habitually lying. His emotional aspect wants to override his/her mentality. His conscience continues to flounder and self-esteem is losing. Observe an infant or a baby, can they practice their mentality or do they just follow their emotion and instinct? A toddler? an adolescent? What about an adult who is so possessed with self and emotions rather than the principles and truth from God's word?
There is no neutral ground in the mentality's choosing ability. If you follow your own ways, it is self-centered,
and degenerates as it ages.
If the basis for your choices is God's printed instruction you get His benefit of regeneration and the soul grows in maturity.
You see faith decision is just an agreement to the completed work of Jesus Christ. God gave the 100% work unto salvation, man says yes, I chose to appropriate that for my life."
Still the choice is yours...is ours.... is mine
Conduit means a passageway or a reservoir. God's formula for salvation is that man's mind need to understand and choose; that is man's part to believe the Gospel, then God performs His promise. The work is completely done on the cross, man's part is to agree/decide or choose that what Jesus Christ did was complete. Salvation is 100 % work of God. There is no faith that can be handed down, every person at his/her age of accountability is expected by God to exercise a personal choice and faith regarding his /her future and destiny.
