Firstly Christians should be obeying the scriptures as that is how the Spirit leads
After being saved for decades, meeting and having fellowship with many leaders at certain events and conferences, doing ministry work I have come to the conclusion that many believers and leaders are not regularly lead by the Holy Spirit.
Too much guess work, emotional decisions, carnal attitudes and personal choices take precedence over God's leading. Of course when they have to address the church they have to assume and tell the church they are being Spirit lead.
Fortunately God is gracious and still works among all the human activity pretending to be the Holy Spirit. Miracles and many blessings can still occur among all the flesh - which is more a sign of God's goodness.
This can vary from church to church and in denominations with some far more open to the Holy Spirit and others basically spiritually deaf.
