How do Protestants who believe in predestination interpret "plant" in [Matt 15:13](https://www.biblegateway.com/passage/?search=Matthew%2015%3A13&version=ESV) : > He answered, “Every plant that my heavenly Father has not planted will be rooted up. Should the plants be understood as *expression* seeds (similar in concept to The Parable of the Sower, [Matt 13:1-23](https://www.biblegateway.com/passage/?search=Matthew+13%3A1-23&version=ESV)) or *people* seeds (Parable of the Weeds, [Matt 13:24-30](https://www.biblegateway.com/passage/?search=Matthew+13%3A24-30&version=ESV)) ? - a) If the plants refer to v9 (vain teachings) and v18-19 (evil thoughts being expressed) then is Jesus saying all of these **thing** seeds (works?) will be burned up when tested (Proverbs 17:3, 1 Corinthians 3:15, etc)? - b) If the plants refer to vv. 8 & 14 (false and blind leaders, **people** seeds) then what is the significance of the phrase in v. 13 I have marked in bold: "Every plant that my heavenly Father **did not plant** will be pulled up by the roots" ? Would this be the same as Matt 13:24-29 (Parable of the Weeds) where God plants some people, and the Enemy plants others, but only God can tell them apart and has the authority to separate them? How do Protestants who believe in predestination apply these 2 parables in connection to the ideas of Predestination & Free will and the Elect/Called/Chosen?
