Repent, or else I will come to you quickly and will fight against them with the sword of My mouth. Revelation 2:16 NKJV
Just as Balaam was killed by the sword because of his involvement in getting the Israelites to sin, those that taught the doctrines of Balaam and the Nicolaitans would also receive their punishment for misleading the people. The only way to avoid judgment is to repent.
For the word of God is alive and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart. (Hebrews 4:12 NIV)
