There are many foolish tares in the church today.
The tares are those who believe that they are saved in their sins by the blood that Jesus shed on cross. They try to claim that they are saved from their sins yet they continue to walk in them.
This is the epitome of foolishness.
Those that do this, and they are many, are perishing despite their beliefs to the contrary.
This is the most dangerous condition anyone can find themselves in. The cross is preached foolishly today and especially every Sunday mornings and evenings and on Wednesday nights as well. If the gospel is preached in a way where the message includes directly or indirectly that sins can go on without genuine repentance then that is not just foolishness but it is an abomination unto the Lord. For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.  For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.  For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.  Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world? 1 Corinthians 1:17-20 Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field:  But while men slept, his enemy came and sowed tares among the wheat, and went his way.  But when the blade was sprung up, and brought forth fruit, then appeared the tares also.  So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in thy field? from whence then hath it tares?  He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up?  But he said, Nay; lest while ye gather up the tares, ye root up also the wheat with them.  Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.  Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us the parable of the tares of the field.  He answered and said unto them, He that soweth the good seed is the Son of man;  The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one ;  The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels.  As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world.  The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity;  And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.  Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear. Matthew 13:24-30,36-43
