1 Timothy 6:4

he is puffed up with conceit and understands nothing. He has an unhealthy craving for controversy and for quarrels about words, which produce envy, dissension, slander, evil suspicions,

Let me tell you that the envy, dissension slander and evil suspicions that took hold in my life ate me up.  

Avoid at all costs the temptation to separate yourself from your brother over some insignificant finding or doctrine.  No one cares what I think about the location of the New Jerusalem, or where the Ark of the Covenant is, when all they see is dissension, disunity and continual bickering.   

Titus 3:3

For we ourselves were once foolish, disobedient, led astray, slaves to various passions and pleasures, passing our days in malice and envy, hated by others and hating one another.
