We've all heard of the phrase 'one bad apple don't spoil the whole bunch.' Well, if you are not careful with your fruit, one can and will. I did a little experiment with apples where I purchased two bags of fresh ripe apples. I took one bag of fresh ripe apples and placed a rotten [decomposing] apple amongst them, while leaving the second bag of fresh ripe apples with like apples. Turns out the ripe apples remained ripe and eatable for the period intended, but the apples with the decomposing apple amongst them also decomposed... prematurely.
Come From Among Them
One bad apple can spoil a bunch. "A little yeast works through the whole lump of dough (Galatians 5:9). It only takes one bad person with bad intentions, motives, actions, thoughts, words, and deeds to infect; corrupt, the quality, character, and actions of others.
"Don’t be tied up as equal partners with people who don’t believe. What does righteousness share with that which is outside the Law? What relationship does light have with darkness? What harmony does Christ have with Satan? What does a believer have in common with someone who doesn’t believe? What agreement can there be between God’s temple and idols? Because we are the temple of the living God. Just as God said, I live with them, and I will move among them. I will be their God, and they will be my people. Therefore, come out from among them and be separated, says the Lord. Don’t touch what is unclean. Then I will welcome you. I will be a father to you, and you will be my sons and daughters, says the Lord Almighty (2 Corinthians 6:14-18).
