Religion can be described as the service, belief and worship of a super human controlling power of especially a personal God or gods.
From various authority sources on human behavior it is obvious that human nature has spiritual dimensional need. In other words humans are wired to long for relationship with supernatural.
Maslow in 1943 identified intellectual and spiritual dimension of human nature, with its attendant self-actualization need. This aspect of human need creates a vacuum in human nature which people intend to fill by belief system known as “Religion”
The scripture explained this to be as result of separation that happened in the Garden of Eden.
From time immemorial various suggestions, has been offered to fill this aspect of human need, which turned out theories and hypothesis better known as religious doctrines.
God and Devil’s involvement
God and the devils’ involvement has been in response to this specialized need of man for obvious different objectives. For instance God manifested Himself to Abraham and made His covenant with him. He gave a set of rules and doctrines to Abraham descendants, which till today forms basis of Judaism as a religion.
Devil on the other hand hijacked this situation by manifesting as angel of light to vulnerable victims by posing as an impostor of Most High God or His agent. The end results False Religion.
The situation however produced religious natural man, which is still unstable, unpredictable and wicked, though religiously informed.
Both True and False Religion failed to produce God’s desired result.
The turnout of event, though obviously known to God beforehand, precipitated confusion, deception, ignorance and foolishness on the part of man and necessitated the need for manifestation of Jesus Christ.
Yes, it is as a result of this that God manifested JESUS, for the purpose of providing solution to the most nagging problem of mankind, which is majorly IGNORANCE.
1John 3:8b For this purpose the Son of God was manifested, that he might destroy the works of the devil.

Conclusion
It is however disheartening to still observe today that, more than 2000 years after these discoveries man still love RELIGION so much, that it is still responsible for major problems confronting man today on a global scale. Religious groups has increased over years, while denominations and factions within each religious group has been ever increasing.
After the ascension of Christ the FAITH in Him disintegrated to Christianity in Antioch. Later Christianity further disintegrated to factions of orthodox and Protestants. Factions further disintegrated to denominations and now denomination is disintegrating to false teaching groups,
No wonder Christ doubted whether He would meet FAITH again upon His return to earth.
Man built religion around Gods will, but JESUS, the Way, the TRUTH and LIFE revealed to us the mind of God. Little wonder He lamented whether He would still meet faith on His return to earth.
The Idea now is not to abolish religion, but it should be great if all religion can be synchronized with the truth JESUS. Shalom.
