This is one of Jesus's many warnings about avoiding false prophets and false Christ's. (
Mat 24:21-28) He said we identify false Christians by their fruits. He said we work the works of God was putting faith in the words of Christ. (
John 6:28-29) God's only later day command is for us to listen to Jesus. (
Mat 17:5 and John 1:12; 8:26 and 15:15) We are
Christians if we are followers of Jesus... Bad fruit is thus working to get you to follow some sect of men, making you believe you need them in your life in order to know God. You don't! (
Mark 3:31-35 Plus) You need to know Jesus by your own personal familiarity with his words... Let me say again, anyone trying to get you to believe you need to follow
their sect is offering you bad fruit. (
Gal 1:6-9)
Jesus further warned in verses 22 and 23 about those who would try and imagine they were Christians when they weren't.
Religionist's saying their sectarian memberships are your hope and protection is who he was warning about!
