What you seem to be advocating is that God is "speaking to people in their hearts." Furthermore you seem to support the idea that we should be guided by subjective feelings that we can just willy nilly CALL the Holy Spirit.
I am challenging you to support this notion with Scripture.
The Bible often uses the word "heart."
It refers to the mind.
Out of the abundance of the heart man speaks.
"The heart is deceitful above all things and desperately wicked." However that is more descriptive of the unsaved heart.
The word "heart" is used 99 times in the NT alone.
Matthew 12:35 A good man out of the good treasure of the heart bringeth forth good things: and an evil man out of the evil treasure bringeth forth evil things.
Luke 24:25 Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken:
--What was slow to believe?
John 12:40 He hath blinded their eyes, and hardened their heart; that they should not see with
their eyes, nor understand with
their heart, and be converted, and I should heal them.
--What is hardened? What understands?
Yes, God speaks to our hearts (our minds). This is a definite teaching of the Bible. He did in the time of Christ; why shouldn't he now. Christ taught his disciples, and then promised that when he left them he would send them the Comforter, and He would continue to teach them. He still does today.
As late as 90 A.D. or later John wrote:
1 John 2:27 But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him.
--The anointing that they received and abided in them is the Holy Spirit. He dwells in all of us who believed in Christ.
That same Spirit teaches us of all things. He is truth.
He had already said to them:
1 John 2:20 But ye have an unction from the Holy One, and ye know all things.
The Holy Spirit teaches. The Holy Spirit guides.
Man is an emotional creature. God made him with emotions.
Many of the fruits of the Spirit are expressed in emotions: Love, joy, peace.
In John 16:24 Jesus promised joy; joy to them that would pray in his name.
He promised peace to those who spent time in prayer:
Philippians 4:6 Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
7 And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
Paul prayed for the Ephesians that they would know and experience the love of Christ:
Ephesians 3:19 And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.
We are not robots simply responding to the mechanics and instructions given in the Word. John was directed to Japan by the Holy Spirit. How and why? Why not China or some other nation? The Holy Spirit spoke to his heart and gave him inner peace about Japan.
Before setting out for the mission field that my family served in, we prayed for at least six months. Then the Lord gave us peace that that is where we should go. It is not, "we convincing ourselves." Rather it is waiting for the Lord to guide us according to his will. What is his will for your life? How do you know?
James 4:15 For that ye
ought to say, If the Lord will, we shall live, and do this, or that.
