One of the things by which the Holy Spirit of God can be grieved is, because a person is not walking correctly in the way of the Lord, doing things that are not pleasing to God.
Many are immature in the faith, others because do not know who the Holy Spirit of God is, nor do they know its definition, and that is why we must teach the new believers and those who do not yet know about the Holy Spirit of God. That is why we should study the Holy Word of God, because in it we will find the answers to our doubts.
And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
The Holy Spirit of God was left to be with us every day until the Son comes for His people, as Jesus said before going to the Father.
He left His Holy Spirit, so that in difficult moments He will encourage us, give us strength, so that He will give us an understanding of His Word. Jesus left His Holy Spirit because He knew that we would have weaknesses at some point, John 14:26 says “But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you”.
Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice:
When we come to Christ everything must change in our lives, and this is because the Holy Spirit is in us, and if it is in us all anger, all malice, anger, screaming, bitterness, it has to go away because the Holy Spirit brings joy to our lives.
And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.
And that is why we must have love, peace, mercy with others, be kind, compassionate, and forgive everyone who has offended us, because the Father also forgave us, and we must help anyone who does not have any of these fruits already mentioned, so that they too can be saved and the Holy Spirit can dwell in their lives.
