Is it possible that the Heavenly Father would allow his true word, laws, and religion to be corrupted?

Look back to the early history of the Israelites in the land of Canaan as recorded in the Old Testament.  Were the true laws and religion given by the Creator corrupted back then?  Yes they were.  And so it is the same all down through history since that time until today.

As revealed in the Word, the Most High allows false teachers and doctrines to be introduced as a TEST, to find out who among his people truly love Him and will be found worthy to inherit eternal life.

Read carefully the true word from the Most High:

Deuteronomy 13:1-5

If a prophet, or one who foretells by dreams, appears among you and announces to you a sign or wonder, 2 and if the sign or wonder spoken of takes place, and the prophet says, “Let us follow other gods” (gods you have not known) “and let us worship them,” 3 you must not listen to the words of that prophet or dreamer. The Lord your God is testing you to find out whether you love him with all your heart and with all your soul. 4 It is the Lord your God you must follow, and him you must revere. Keep his commands and obey him; serve him and hold fast to him. 5 That prophet or dreamer must be put to death for inciting rebellion against the Lord your God, who brought you out of Egypt and redeemed you from the land of slavery. That prophet or dreamer tried to turn you from the way the Lord your God commanded you to follow. You must purge the evil from among you.

Also remember the words of the Messiah, who sternly warned against false prophets to come who would “shew great signs and wonders”, and the teachings of the Pharisees in particular.

Matthew 7:15-20

15 Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves. 16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? 17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. 18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. 19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. 20 Wherefore by their fruits ye shall know them.

Matthew 16:6

“Then Jesus said unto them, Take heed and beware of the leaven of the Pharisees and of the Sadducees.”

Matthew 24:24

“For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect.”
