Matthew 13:30 says”Let both grow together until the harvest. At that time I will tell the harvesters: First collect the weeds and tie them in bundles to be burned; then gather the wheat and bring it into my barn.'”
Many who are not in the body through the conversion of Christ resemble those who are. Just like true Christians, they go to church, pray, and read the Bible, but they are only religious hobbyists. Jesus calls them “sons of the wicked one” Matthew 13:38, and being tares, they will be destroyed. The tares are not originally from the wicked one, but they develop character according to his strong influence. They are led by him and so are his children , who‘s children are we talking about? We are talking about the evil children. John 8:44
The genuine Christians and the counterfeit Christians wheat are always together in the church. Do you know why? Because they want to mimic the original so that they can profit from it. Then the wicked ones go out and convince others that they are children of God for this is why the world and other real saints sit back and wonder how can you call yourself a child of God and yet act like the sinner? Come on somebody, help me here!
First, we need to be aware that tares—false members—are a reality. Counterfeit members do exist and are at work within God’s church; Christ Himself says so. The fact that they are present requires that we be on our guard, not allowing ourselves to be led a stray.
For false christ and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect.” Knowing that tares are in the church, we must be vigilant, clinging to the truth lest we be deceived.
