A highway shall be there, and a road,
And it shall be called the Highway of Holiness.
The unclean shall not pass over it, But it shall be for others. Whoever walks the road, although a fool, Shall not go astray. (Isaiah 35:8)
Is this the narrow road, Jesus spoke of?

I believe so. And be on the watch, for this road does have warning signs, such as we find in 2 Cor chapter 6:
For this reason,
“Come out from among them and be separate,” says the Lord.
“Touch nothing that is unclean, and I will embrace you. (2 Cor 6:17. TPT)
What was the reason?
Don’t continue to team up with unbelievers in mismatched alliances, for what partnership is there between righteousness and rebellion?
Who could mingle light with darkness?
What harmony can there be between Christ and Satan?
Or what does a believer have in common with an unbeliever?
What friendship does God’s temple have with demons?
For indeed, we are the temple of the living God, just as God has said:
I will make my home in them and walk among them. I will be their God, and they will be my people. (2 Cor 6:14-16, TPT)
This means to walk in purity, do not associate with those who teach contrary to that which the Word teaches. Jesus and Paul both warn us of of false teachers and flase doctrines that run contrary to that which is truth.
The dangerous delusion of these perverse doctrines is seen in how they appear to be holy & righteous, yet they contain just enough of a twist that is so subtle, many will be they who are fooled and led astray.
Again, Jesus gave us this warning:
For there will be imposters falsely claiming to be God’s ‘Anointed One,’ and false prophets will arise to perform miracle signs to lead astray, if possible, those God has chosen to be his. (Matt 24:24, TPT)
There are times it may be very difficult in having discerned such false teachings and warning others, yet they chose not to listen.
Because of our love for them, do we throw caution to the wind and stay under such teachings or ministries?
NO.
We can clearly see here in 2 Cor chapter 6, how Paul is laying the foundation as to a Kingdom standard that we must not dismiss! The Word is clear: “Come-out from amongst them”. In in other words let your separation be so evident, that there will be absolutely no room to suggest your still connected to such.
DO NOT let your ternary of effection cause you to stay…for you and your whole family will be subject to paying a great price in all areas of your life.
Now, look at how the reward of being obediant to this warning blesses us:
FOR THIS REASON…….
“Come out from among them and be separate,” says the Lord. “Touch nothing that is unclean,
AND I will embrace you. I will be a true Father to you, and you will be my beloved sons and daughters,” says the Lord Yahweh Almighty. (2 Cor 6:17-18, TPT)
Boom, YAY GOD!!!
Holy Spirit, I ask that You keep me on Yahweh’s Highway of Holiness regardless of the cost.
