But he who is greatest among you shall be your servant. And whoever exalts himself will be humbled, and he who humbles himself will be exalted. Mt 23:11-12
Nicolaitans and soul-winners approach Christian service from opposite directions. Nicolaitans see Christian service as an opportunity to be leaders, while soul-winners see Christian service as an opportunity to be servants. Later, we often see Nicolaitans with unsuccessful ministries, while soul-winners are successful in theirs. The reason is that God blesses humility, but He resists pride.
2 Ch 7:14 tells us "if My people who are called by My name will humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and will forgive their sin and heal their land." WHY does this work? Because part of humbling yourself is admitting that something is wrong. But once a Nicolaitan has seized power, he feels that everything is as it should be.
