We have at one time or another met those who seem to be set on doing that which is wrong. We may ask ourselves why does God allow wickedness and evil to dwell in the earth? Jesus taught a very good lesson in the parable of the sower and how tares(weeds)grow alongside the wheat(Matthew 13:36-43). 36 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.37 He answered and said unto them, He that soweth the good seed is the Son of man;38 The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one;39 The enemy that sowed them is the devil; the harvest is the end of the world; and the reapers are the angels.40 As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world.41 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;42 And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.43 Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear.
We are given instruction to not accept the person who is wicked, because if we follow righteousness and accept the wicked then we are saying they are doing what is right and it makes our right look wrong!(Proverbs 18:5).
Scripture teaches us sound advice when it comes to being obedient as a christian, and as children of light we are not to be accepting of those who choose the darkness of disobedience.(Ephesians 5:6-17). 6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience.7 Be not ye therefore partakers with them.8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:9 (For the fruit of the Spirit is in all goodness and righteousness and truth;)10 Proving what is acceptable unto the Lord.11 And have no fellowship with the unfruitful works of darkness, but rather reprove them.12 For it is a shame even to speak of those things which are done of them in secret.13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.15 See then that ye walk circumspectly, not as fools, but as wise,16 Redeeming the time, because the days are evil.17 Wherefore be ye not unwise, but understanding what the will of the Lord is.
Proverbs 15:28-2928 The heart of the righteous studieth to answer: but the mouth of the wicked poureth out evil things.29 The Lord is far from the wicked: but he heareth the prayer of the righteous.
