Text:“Every plant, which my heavenly Father hath not planted, shall be rooted up. Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.” - Matthew 15:13, 14.
This text shows clearly that it is not every organisation that calls on the names of God Almighty that belongs to Him. While God allows other religions or faiths to exist alongside the true faith or His Church, all false religions shall be exposed and destroyed by God in the end. But God will never mandate anybody to do that for Him. That was why when the disciples of Christ told him that the Pharisees took offence at his teaching he made the statement in the text for the day. For all their self-righteousness and pride the system of religion of the Pharisees was more of rituals and formalities than real substance. For this they were constantly chastised by Jesus Christ. They therefore sought by every means to destroy his influence among the people.
It is vital that everyone should constantly examine his beliefs in the light of the Scriptures to be sure he is following the truth, lest all the exertions and sacrifices be in vain. When John the Baptist saw the Pharisees and Saducees coming to him for baptism he said unto them: “O generation of vipers, who hath warned you to flee from the wrath to come? Bring forth therefore fruits meet for repentance…” - Matthew 3:7-10.
