But he gives more grace.     Wherefore he says, The Lord resists the proud, but gives grace unto the humble. Jam 4:6 This is a Spiritual Law.     pride cuts off the flow of Grace from the Lord.     He is not offended by pride but He simply has determined that it will not be blessed and so will result in the proud being abased.     Whereas, humility opens the floodgates to the Lord's Grace enabling the humble to be lifted up.

Pride goes before destruction, and an haughty spirit before a fall. Pro 16:18

Every one that is proud in heart is an abomination to the Lord: though hand join in hand, he shall not be unpunished. Pro 16:5

He, that being often reproved hardens his neck, shall suddenly be destroyed, and that without remedy. Pro 29:1

These verse make it very clear how God feels about pride.   

There are many people who have adopted the attitude of Satan toward God.   

I will ascend above the heights of the clouds; I will be like the most High. Isa 14:14

They have made themselves god.   

Their rejection of the Gospel delivered by the Holy Spirit through the children of God is likely the offense that Jesus was referring to.   

And whoever shall speak a word against the Son Of Man, it shall be forgiven him: but unto him that blasphemes against the Holy Spirit it shall not be forgiven. Luk 12:10 The Son Of Man is the Lord in flesh and we call Him Jesus.      Our Lord makes a distinction between the physical and spiritual manifestation of the Lord.     He understands how people looking at His flesh and listening to His voice may say something against Him.     But the Holy Spirit by which He spoke is pure the Lord.     To reject and blaspheme the Holy Spirit is unconsciounable.      The Holy Spirit draws a person to faith in Christ.     By offending the Holy Spirit, they will never be drawn and so they will never be saved.

No one can see the Holy Ghost or speak to Him except by seeing and speaking to Spirit Filled Christians sharing the Testimony Of Jesus Christ.
