@A_Thinker,
The Christian life pivots on faith, right? We can never have too much faith. Jesus said that anything is possible for he who believes. Our success against the enemy is wholly dependent on faith.
Now for the point. The Inward Witness (direct revelation) is our ongoing source of saving faith where faith is defined as a
feeling of certainty. I discussed on how Heb 11 attributes all the great acts of faith to faith defined in that way - a feeling of certainty obtained from direct revelation.
This is straightforward. "Faith cometh by hearing" - hearing the divine Word/Voice (not Scripture). In Rom and Gal both, Paul's favorite example is Gen 15:1 where "The Word of the Lord came to Abram" speaking promises. Hearing God speak promises gives me confidence (faith) in those things.
So let's suppose it's our ambition to heal a sick person. We have to pray until we get the assurance (the feeling of 100% certainty) that God has said Yes. This is faith.
Or let's say we think God might want us to do missionary work. We have to pray until we get the 100% feeling of certainty in our heart that God has said Yes. This is faith. (Note how Paul's missionary work was directed by signs and visions - Acts 16:6-10). Charles Finney's success was based on applying this principle - thus he figured out the correct
practice even though,
doctrinally, he himself never explicitly formulated the correct epistemology. Pastor Yonngi Cho (arguably the most successful pastor in church history) also used the same approach even without really understanding biblical epistemology.
In particular Cho would pray for a particular individual to be saved until God said Yes. Finney often did the same thing. Cho also said that, whenever a major church decision had to be made, his staff would pray and fast with him until they got the full assurance (the 100% certainty) of which direction to take.
However, because the church for the most part has NOT been taking this kind of approach for the last 2000 years, we are very distant from God and thus stuck in a terrible dry season. This means we generally won't get answers to prayer (we won't often hear God's voice very loud and clear for example) but nonetheless we still need to practice the right approach because it's the only way to get back on course so that we hopefully can get OUT of this horrible spiritual famine.
Of course we also might get lucky. God might send us a revival out of the blue, thereby pulling us out of the dry season.
