If you eat deception, you will give that to others to eat and you will be responsible for the outcome.
That delicious apple that Eve ate and then gave to her husband represented deception.
Deception causes division between God and man.
If one eats of it, it will be difficult to commune with God.
For a good tree bringeth not forth corrupt fruit; neither doth a corrupt tree bring forth good fruit. Luke 6:43
That is why we are told we must love the truth.
Deception might have some truth in it, but it is not truth.
Without the truth abiding in us, we will not produce good fruit.
(For the fruit of the Spirit is in all goodness and righteousness and truth;) Ephesians 5:9
Abide in Me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine;
no more can ye, except ye abide in Me. John 15:4
Jesus talked about waiting until the end, the time of harvest,
before He would separate the wheat from the tares.
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. Matthew 13:30
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 13:41-43
We must be very careful about the fruit we eat as we will then produce that same type of fruit.
