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 Holy Spirit in flesh and we call Him Jesus.      Our Lord makes a distinction between the physical and spiritual manifestation of the Holy Spirit.     He understands how people looking at His flesh and listening to His voice may say something against Him.     But His Holy Spirit by which He spoke is pure God.     To reject and blaspheme His 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.   

So, they BlasphemeTheHolyGhost who comes to them in the witnesses of Christ Jesus.   

Jesus is Creator, Mighty God, Savior, Healer, Deliverer, Judge, Lord and King.   

Who does a person think they are in turning His offer of Grace down?   

To blaspheme is to denigrate.   You can denigrate out loud or just in your mind.   

When a witness for Christ Jesus delivers the Gospel to a person it is the Holy Spirit of Christ Jesus who draws them.   

So, when that person turns down the Grace offered by the Word and Holy Spirit they have effectively denied the deity of the Word and Holy Spirit and treated Him as a liar and a fraud through their unbelief.   
At any rate they have denied Him His property as we were bought with the price of His blood.   

So, do not cast your Pearls Before Swine.   
Do not blaspheme Christ by begging people to believe on Him and receive His Grace.   

Preach, teach and testify the Gospel in the AuthorityAndPower of Jesus Christ.   

Remember,
   ➛ Jesus never healed anyone who resisted Him.   
   ➛ He never begged anyone to follow Him.   
   ➛ He never chased after any unbeliever.   

It is not your love that saves a person.   
It is the love of God as manifested in Christ Jesus, His Word and His Holy Spirit.   

Listen to the message Paul received from the Lord after disputing (teaching and arguing) the Gospel with people:

Then spoke the Lord to Paul in the night by a vision, Be not afraid, but speak, and hold not your peace: Act 18:9 When the Holy Spirit confirms a Word to you, you are to speak it boldly and unapologetically,

We are to be BOLD in our Testimony Of Jesus Christ.   
   ➛ He is King
   ➛ we are His brothers
   ➛ we are Sons Of The Holy Spirit
   ➛ we are a Royal Priesthood.
